After the 15℅ sales tax the jeans were $11.50 how much was the jeans before the sales price

$10

Step-by-step explanation:

The price of the item before tax is 100% of its price since 100% means the entire thing.

When you add a 15% tax, the total price (including tax) is now 115% of the original price.

The original price is unknown, so we call it x.

115% of x is $11.50

115% * x = 11.50

1.15x = 11.5

x = 10
