then n =

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

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%
