Question

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

Answer 1

Total = 83.39

Hat = 37.89

J = Jersey cost

0.7*J = Jersey cost + discount

T = H + 0.7J

`\begin{gathered} T=H+0.7\cdot J \\ T-H=0.7\cdot J \\ J=(T-H)/(0.7) \\ J=(83.39-37.39)/(0.7) \\ J=(46)/(0.7) \\ J=65.71 \end{gathered}`

The Jersey cost was $65.71
