sashaice [31]

Answer: $20

Step-by-step explanation:

Here os the correct question:

Stephanie saw in an ad in the paper that her favorite kind of perfume was on sale for 25% off. If the sale price was $15, what was the original price of the perfume?

Let the original price of the perfume be y.

Since we are told that 25% is off, that means that 25% has been deducted from the original price. This can be written as:

y - (25% of y) = $15

y - (25/100 × y) = $15

y - 0.25y = $15

0.75y = $15

Divide both side by 0.75

0.75y/0.75 = $15/0.75

y = $20

The original price of the perfume is $20

ra1l [238]

Answer:

A = 10.5%

B = 28.9%

C = 39.5%

D = 18.4%

F = 2.6%

Step-by-step explanation:

  • 11/38 × 100 = 28.9%
  • 15/38 × 100 = 39.5%
  • 7/38 × 100 = 18.4%
  • 1/38 × 100 = 2.6%

10.5 + 28.9 + 39.5 + 18.4 + 2.6 = 100%
