Question

Greg is selling T-shirts for the basketball team as a fundraiser. The total amount earned for the team ,y, is proportional to the number of t-shirts ,x, Greg sales. The team earns $7.50 for each t-shirt sold. Which equation represents the total amount Greg earns for the team?A) y=$7.50/xB) y=x+$7.50C) y=$7.50xD) y=x/$750

Answer 1

To do this you can proceed as follows:

`\frac{\text{Total amount earned for the team - y}}{\text{ The number of t-shirts - x}}=\text{ \$7.50}`

Solving for you get

`\begin{gathered} (y)/(x)=7.50 \\ \text{You multiply both sides of the quality by x} \\ (y)/(x)\cdot x=7.50x \\ y=7.50x \end{gathered}`

Therefore, the correct answer is C) y=$7,50x.
