Question

Tyrone went to a basketball game and bought a jersey that was on sale at a 30% discount. He also bought a hat that cost $37.89. Tyrone spent a total of $83.39. Write an equation to find the original cost of the jersey.

Answer 1

Answer: Let x be the original cost of the jersey.

We know that the jersey was on sale at a 30% discount, so the sale price is x - (30/100)*x = x(1- 0.3) = 0.7x

We also know that Tyrone spent a total of $83.39 and the hat cost $37.89, so the jersey cost is 83.39 - 37.89 = 45.5

So we can write the equation:

0.7x = 45.5

To find the original cost of the jersey, we can divide both sides by 0.7:

x = 45.5 / 0.7

x = 65

So the original cost of the jersey is $65.
