A park meadow is planted with wildflowers. The Parks Department plans to extend the length of the rectangular meadow by x meters. Which
expressions represent the total area, in square meters, after the
meadow's length is increased? Select all that apply.

A 310 + x
B 15.5(20x)
C 20x + 15.5
D 15.5x + 310
E 15.5(20 + x)
F 35.5 + 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%

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
