Question

Anita attends a private school where she must wear a uniform. This year, the price of the uniform is $86.80, which is 9.6% more than it cost last year. How much were uniforms last year?

Round your answer to the nearest cent.

Answer 1

Below

Explanation:

x = price last year

x * .096 = price increase (.096 is 9.6% in decimal form)

price THIS year is x + x * .096

= 1.096 x

so:

86.80 = 1.096 x divide both sides of the equation by 1.096

79.20 = x = original price
