The flip flops were on sale for a 33.33% discount.
What is a discount?
To find the percent discount on an item, we can use the formula:
Discount % = (Original price - Sale price)/Original price * 100
In this case, the original price of the flip flops is $45.00 and the sale price is $30.00. Substituting these values into the formula, we find that the discount percent is:
Discount % = ($45.00 - $30.00)/$45.00 * 100 = $15.00/$45.00 * 100 = 1/3 * 100 = 33.33%
Hence, the flip flops were on sale for a 33.33% discount.
