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

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
