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.
Dmitry [639]

Answer:

Jersey cost (without discount)= $65

Step-by-step explanation:

<u>First, we need to determine how much he spent on the jersey:</u>

Jersey cost (with discount)= 83.39 - 37.89

Jersey cost (with discount)= $45.5

<u>Now, the original cost of the jersey:</u>

Jersey cost (without discount)= discount cost / (1 - discount)

Jersey cost (without discount)= 45.5 / 0.7

Jersey cost (without discount)= $65
