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.

Respuesta :

Total = 83.39

Hat = 37.89

J = Jersey cost

0.7*J = Jersey cost + discount

T = H + 0.7J

[tex]\begin{gathered} T=H+0.7\cdot J \\ T-H=0.7\cdot J \\ J=\frac{T-H}{0.7} \\ J=\frac{83.39-37.39}{0.7} \\ J=\frac{46}{0.7} \\ J=65.71 \end{gathered}[/tex]

The Jersey cost was $65.71
