Answer:
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%
