The band sponsored a car wash. During the first session, the students earned $78. During the afternoon session, they earned $54. That evening when people were on
their way home from work, the students earned $81. If the band charged a whole
dollar amount for each car, what was the charge per car?

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount
