En una tienda se anuncia la rebaja de 20% en todos sus artículos . Rafael elije una camisa y al llegar a la caja le informan que sea camisa , por traer etiqueta roja . Cuenta con un descuento adicional de 15% . Si Rafael pago $510.00 , cuál era el precio de la camisa sin los dos descuentos
Responder:
$ 750
Explicación paso a paso:
Dado que :
Descuento en todos los artículos = 20%
Descuento adicional dado = 15%
Monto final pagado por la camisa = $ 510
Precio de la camiseta sin descuento:
Sea el precio inicial de la camisa = x
Primer descuento obtenido = 20%
Precio pagado después de un descuento adicional del 15%
Primer descuento:
(1 - 0,20) * x = 0,8x
Segundo descuento:
(1 - 0,15) * 0,8x = 510
0,85 * 0,8x = 510
0,68x = 510
x = 510 / 0,68
x = $ 750

Denise bought 116 ounces of beans for a bean dip. She bought both 15-ounce cans and 28-ounce cans, and the total number of cans she bought was 6. Which of these systems of equations can be used to determine the number of 15-ounce cans and the number of 28-ounce cans that she bought? Assume x represents the number of 15-ounce cans and y represents the number of 28-ounce cans.
x + y = 6. 15 x + 28 y = 116.
x + y = 6. 28 x + 15 y = 116.
x + y = 116. 15 x + 28 y = 6.
x + y = 116. 28 x + 15 y = 6.
Mark this and return
Answer:
15x + 28y = 116
x + y = 6

If you place $2000 in a savings account that generates 4% interest. How much simple interest will you earn over3 years?
You roll a fair six-sided die. The die shows an even number or a number greater than four .
Solve it (NOT MULTIPLE CHOICE) find the probability:)
Answer:
4/6
Step-by-step explanation:
There are 3 ways to get an even number: 2, 4, 6 -> chance is 3/6=1/2
There is 1 way to get a number greater than 4: 5 (because 6 was already counted) -> chance is 1/6
Add up the probabilities: 1/2 + 1/6 = 3/6 + 1/6 = 4/6
The probability of rolling an even number or a number greater than 4 is 4/6
Klein opened a savings account that paid 5% simple interest with 6,000 in principal. If Klem left that money untouched in the account for ten years,then how much interest with he have earned?
Answer:
I= $3,000
Step-by-step explanation:
Giving the following information:
Klein opened a savings account that paid 5% simple interest with 6,000 in principal.
Number of periods= 10 years
To calculate the interest earned, we need to use the following formula:
I= P*r*t
P= principal
r= interest rate
t= time
I= 6,000*0.05*10
I= $3,000

NEED HELP FAST!!!!!
20 points pls
Answer:
A. because both variables (y and x) cancel each other out because they are equal. The answer to A is 0=6, which is clearly not true. All other choices have a solution that is possible, because at least 1 of the variables doesn't cancel itself out.

Two cards are drawn from a pack of 52 cards one by one without replacement; that is, the first card is not replaced before the second card is drawn. What is the probability of the second card being a king of spades if the first card is a king of club
Answer:
The probability is 1/51
Step-by-step explanation:
In a deck of cards, there are 52 cards
one king of spades and one king of club
If the first is a king of club, after drawing it, the number of cards that we will have left will be 52-1 = 51 cards
So the probability that the second is a king of spades is the number of king of spades/number of remaining cards
Mathematically that will be 1/51

A car costing $125 000 may be paid for in any of the following ways:
Scheme A: By cash full payment.
Scheme B: A deposit of 40% of the cost plus 72 monthly payments of $1500. Which scheme is better A or B?
Show necessary working to justify your answer.
Answer:
Step-by-step explanation
Plan B
40% of 125000 = 40/100 * 125000 = 0.4 * 125000 = 50000
72 * 1500 = 108000
Total 158000
Plan A
125000
Difference 33000
You want to take plan A if you can.
