Alma bought a laptop computer at a store that gave a 20 percent discount off its original price. the total amount she paid to the cashier was p dollars, including an 8 percent sales tax on the discounted price. which of the following represents the original price of the computer in terms of p?

original -.20* original = sales price

original (1-.2) =sales price

original*.8 = sales price

total amount = sales price + sales price*.08

total amount = sales price + sales price*.08

total amount = sales price (1+.08)

total amount = sales price (1.08)

replace original price with p

.8 p =sales price

total amount = .8p(1.08)

total amount = .864p

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

its c or d   take a lucky guess my dude
