Janice bought an antique clock originally priced at $967 but on sale for 5% off. After 1% sales tax, what was the total cost?
Answers
Answer:
927.84
Step-by-step explanation:
The total cost of the antique clock that Janice bought is $927.82 approximately.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For this case, we have:
Original price of clock = $967Sale discount = 5% on original price1% sales tax on the discounted priceTotal cost = (discounted price of clock)'s price + sales tax of discounted price.
Let d = discounted price of the clock
Then, we have:
[tex]d = $967 - \text{5\% discount on 967} \\\\d = 967 - \dfrac{967}{100} \times 5 = \$918.65[/tex]
1% sales tax on 'd' will be: [tex]\dfrac{d}{100} \times 1 = \$9.1865 \approx \$9.19[/tex]
Thus, we get:
Total cost of the clock ≈ 918.65 + 9.19 = 927.82 (in dollars)
Thus, the total cost of the antique clock that Janice bought is $927.82 approximately.

Stella bought 14 purses for $50. The next day she bought 2 more for a total of $38. What was the mean cost per purse?
Answers
Answer:
$48.5
Step-by-step explanation:
Given data
Number of purses= 14+2= 16
Cost of 14 purses= $50
Cost of 2 purses= $38
Let us use the weighted cost method
Mean cost = (14*50+ 2*38)/16
Mean cost = (700+ 76)/16
Mean cost = 776/16
Mean cost =$48.5

Fran solved the equation 42 = x + 23. Although her final answer was correct, she could have found it in a simpler way. Which sentence best explains why? 23 should be added to the left side and 42 added to the right side. 23 should have been subtracted from, not added to, both sides of the equation. 42 should be subtracted from both sides. The variable must be moved to the left side of the equation.

Find the area of the shape
Answers
Answer:
54 unit^2.
Step-by-step explanation:
The area = the sum of the 2 triangles.
Area of a triangle = 1/2 * base * height.
So here:
A = 1/2 * 4 * 12 + 1/2 * 5 * 12
= 24 + 30
= 54
Answer:
ABCD = 54 u²Explanation:
the area of the polygon = the area of the triangle ADC + the area of the triangle ABC
the area of a triangle = (height × base)/2
A ADC = (DE×AC)/2
A ADC = (4×12)/2
A ADC = 48/2
A ADC = 24 u²
A ABC = (BF×AC)/2
A ABC = (5×12)/2
A ABC = 60/2
A ABC = 30 u²
ABCD = A ADC + A ABC
ABCD = 24 + 30
ABCD = 54 u²

Is 14 a solution for the equation -5 + 2x = 23? Explain.
Answers
Answer:
Yes because after solving the equation, x does indeed equal 14.
Step-by-step explanation:
-5 + 2x = 23
2x = 23 + 5
2x = 28
x = 14
Answer:
-5 + 2x= 23 x= 14 (Correct)
Step-by-step explanation:
This is true because the first step you take to sloving this equation is to move the constant to the right. Then calculate. Divide both sides and your answer should equal x=14!

Answers
9514 1404 393
Answer:
c. x = 7-t; y = -1/(t -7)
Step-by-step explanation:
To find the parametric equation for x, use the equation for t and solve for x.
t = 7-x
x = 7 -t . . . . . . add x-t to both sides
__
To find the parametric equation for y, substitute the equation for x.
y = 1/x
y = 1/(7-t)
To make this match the available choices, we need to multiply numerator and denominator by -1.
y = -1/(t -7)
The parametric equations are ...
x = 7 -t; y = -1/(t -7) . . . . . . matches choice C

Someone help me out. So the question is Distance = Rate x Time What is the distance traveled if it took me 3 hours to travel at a rate of 60 miles per hour?
Answers
Answer: 180 miles
Step-by-step explanation:
From the question, we should note that the distance taken will be calculated by using the formula which will be:
Distance = Rate × Time
where,
Rate = 60 miles per hour
Time = 3 hours
Distance = 60 × 3
Distance = 180 miles
Therefore, the distance travelled is 180 miles.
