step-by-step explanation: i just don't

i believe the answer is c.

15: 24

62.5%

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
