The selling price of a skateboard is $147. the store has a 75% markup policy. what is the cost of the skateboard to the store?

Given:
selling price = $147
mark up = 75%

Asked:
original cost

The solution:
Selling price is the sum of the original cost and mark up price. It could be written as following,
Original cost + mark up price = selling price
100% original cost + 75% original = selling price
175% original cost = selling price
1.75 original cost = selling price

Solve for original cost
original cost = selling price/1.75

Plug in the numbers
original cost = selling price/1.75
original cost = 147/1.75
original cost = 84

The original cost of the skateboard is $84

Hello!

the answer is:

the answer is:

why?

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!
