Michelle ordered shirts to sell at the school carnival. She paid $2.80 per shirt, she adds a 150% markup to the total price she paid for the shirts.
What is the selling price of each shirt?

PLEASE HELP!! Any help will be greatly appreciated!

The selling price is $7

Step-by-step explanation:

Step one:

Given information

She paid $2.80 per shirt

She adds a  150% markup to the total price she paid for the shirts

Let us find 150% of $2.80

=150/100*2.8

=1.5*2.8

=$4.2

Hence the selling price is the markup price plus the cost price

=4.2+2.8

=$7
