Question

a store spends $10 for each pair of brand X jeans and adds a 120% markup to the cost what is the selling price of the jeans

Answer 1

100% of $10 is another $10.
20% of $10 is $2.

$10+$10+$2 =

$22.

Answer 2

Well another way is like this you turn 120% into a decimal and then you multiply it by ten and you get 10x1.20=12 and then you keep the first number which is ten add it to 12 and
X=$22
