Mark and his friends ate at a restaurant the subtotal is 52.00 the bill says they need to pay 4.42 in sales tax. What percentage of the subtotal is sales tax

8.5%

Step-by-step explanation:

In this question, we are asked to calculate the percentage of the subtotal is sales tax.

Let the percentage they have to pay be x%

This mathematically means that:

x/100 * 52 = 4.42

52x = 100 * 4.42

52x = 442

x = 442/52

x = 8.5

Hence, x = 8.5%

The percentage of the subtotal that is for sales tax is 8.5%
