To find out the total price firstly we need to calculate how much is 7.5% from 22.50:
22.50 * 7.5% = = 22.5 * 0.075 = = 22 5/10 * 75/1000 = = 22 1/2 * 15/200 = = 45/2 * 3/40 = = 9/2 * 3/8 = = 27/16 = = 1 11/16 = = 1,6875 (done with calculator)
1,6875 after rounding to the nearest cent is 1,69
So the total price is 22.50 + 1.69 = $24.19
The total price of the dress, after adding a sales tax of 7.5% to the original price of $22.50, is $24.19. The sales tax calculated is $1.69 after rounding to the nearest cent. Thus, by adding both amounts, we arrive at the total price.
