This summer, Alban has been selling lemonade for $9 per cup. If Alban has sold 99 cups so far, how much money has he made?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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%

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
