Multiply both sides by three to get 2x=30
Then divide both sides by 2 to get x=15
47.5% in decimal form is 0.475.
Since the price was increased, we add 1 to 0.475 to get 1.475.
80 * 1.475 = 118
Another way to solve this is to multiply 80 by 0.475, which is 38, then add it to 80.
The retail price of the shoes is $118.
