Solve for R:
28=4r+28

r = 0

Step-by-step explanation:

28 = 4r + 28

0 = 4r  (subtracted 28 from both sides)

r = 0  (divided 4 from both sides)

answer is x<

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%
