1 Sally purchases a medication for her dog. She weighs her dog and finds that he weighs
65 pounds. Unfortunately, the medication
dosage is based on weight in kilograms rather
than pounds. If 1 kilogram is approximately
2.2 pounds, which value best represents the
weight of Sally's dog in kilograms?
A 143 kg
B 32.5 kg
C 130 kg
D 29.5 kg

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:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

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