Today, 6 friends went out for lunch. their total bill was $41.88, including tax and gratuity. they decide to split the bill equally and each paid a $10 bill. how much money will each person get back?

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%
