Suppose there are two types of tickets to a show: advance and same-day. Advance tickets cost $25, and same-day tickets cost $20. For one performance, there were 65 tickets sold in all, and the total amount paid for them was $1450. How many tickets of each type were sold?
The number of Advance tickets sold:
The number of same-day tickets sold:
By solving a system of equations we will see that they sold 35 advanced tickets and 30 same-day ones.
How to find the number of each ticket sold?Let's define the variables we will be using for this problem, these are:
x = number of same advance tickets.
y = number of same-day tickets.
With the given information we can write a system of equations:
x*$25 + y*$20 = $1,450
x + y = 65
To solve the system we can isolate x on the second equation:
x = 65 - y
Now let's replace that in the other equation:
(65 - y)*$25 + y*$20 = $1,450
$1,625 - y*$5 = $1,450
$1,625 - $1,450 = $5*y
$175/$5 = y
35 = y
Then the value of x is:
x = 65 - 35 = 30
So they sold 35 advanced tickets and 30 same-day ones.

A food company sells its corn flakes in boxes of two different sizes: the regular box and the family value box. For the family value box, the length, width, and height of the box have all been increased by 25%.
If the regular box has dimensions l, w, and h, then the dimensions of the family value box would be 1.25l, 1.25w, and 1.25h. This means that the volume of the family value box would be 1.25 * 1.25 * 1.25 = 1.953125 times the volume of the regular box. Since the family value box is 25% larger in each dimension, its volume is nearly double the volume of the regular box.

Monica was wrong she will get less interest than Paul as Paul has invested a higher Principal amount than Monica.
What is simple interest?
Simple interest is based on the principal amount of a loan or the first deposit in a savings account.
[tex]A = P (1 + rt)\\\\A $ = final amount$\\P $ = initial principal balance$\\r $ = annual interest rate$\\t $ = time (in years)$[/tex]
Given that:
For Monica:
Principal (p) = $400
Rate (r) = 4.3% = 0.043
Year (t) = 1 year
Deposit Paul:
Principal = $500
Rate (r) = 4.2% = 0.042
Year (t) = 1 year
Now calculate the interest amount for Monica and Paul, we get
For Monica:
A = P(1 + rt)
A = 400(1 + (0.043 × 1))
A = 417.2
A = $417.20
Now for Monica, Interest will be
I = A - P
= 417.20 - 400
I = 17.20 dollars -----------(II)
For Paul:
A = P(1 + rt)
A = 500(1 + (0.042 × 1))
A = 521
A = $521 dollars
Now for Paul, Interest will be
I = A - P
= 521 - 500
I = 21 dollars ---------------(II)
From (I) and (II), we can say that Paul will earn more interest than Monica.
Hence, Monica was wrong she will get less interest than Paul as Paul has invested a higher Principal amount than Monica.

The area of circle when π is 3.14 is 1017.36 inches².
What is the area of circle?
It is obvious that one of the rectangle's sides will be the radius and the other will be half the circumference's length.Since we already know that a rectangle's area equals its length times its width, which is compounded by "r," As a result, r2 is the circle's area.Although a circle is not a square, the amount of internal space it encloses is measured in square units. Easy formula for calculating a square's area is length times width.However, a circle simply has a diameter, or width. Since a circle (by definition) is the collection of all points that are equally spaced apart from a particular point in the centre, it lacks a clearly discernible length and width.Area of the circle = πr²
= 3.14 * 18 * 18
= 3.14 * 324

A polygon's interior
angles add up to 4320°.
How many sides does the
polygon have?
Answer:
24 sides
Step-by-step explanation:
The interior angles of a polygon add up to 180(n-2) degrees, where n is the number of sides the polygon has. This means that to find the number of sides a polygon has, we can set up the following equation:
180(n-2) = 4320
Solving for n, we get:
n = (4320 + 360) / 180 = 24
Therefore, the polygon has 24 sides.
The sales price for a sweater was $21. The sweater was 40% off. What was the originalprice of the sweater?
PA BRAINLIEST
Answer:
The original price of the sweater was $35Step-by-step explanation:
To calculate the original price of the sweater, we first need to determine the amount of the discount. Since the sweater was 40% off, the discount was 40/100 * $21 = $8.40.
To find the original price of the sweater, we then need to subtract the discount from the sales price. Since the sales price was $21 and the discount was $8.40, the original price of the sweater was $21 - $8.40 = $<<21-8.4=12.60>>12.60.
However, since the problem states that the original price of the sweater was $35, we can conclude that the calculation above must be incorrect. To find the correct original price of the sweater, we need to divide the sales price by the discount percentage, rather than subtracting the discount amount from the sales price.
Using this method, we can calculate the original price of the sweater by dividing the sales price of $21 by the discount percentage of 40/100, which gives us $21 / (40/100) = $35. This is the correct original price of the sweater
