Question

Monica paid sales tax of $1.50 when she bought a new bike helmet. If the sales tax rate was 5%, how much did the store charge for the helmey before tax?

Answer 1

Let the cost before the sales tax be x.

Sales tax = $1.50

Since sales tax is 5%, that means 5% of x = 1.5

5% of x = 1.5

(5/100) x = 1.5

0.05x = 1.5

x = 1.5/0.05

x = 30

Therefore the charge is $30.00
