Question

8. A bowling alley costs $6 for shoes and charges $12.50 per game. If you pay $68.50, how many games did you play?

Answer 1

The total cost is 68.50 dollars, and out of this you paid 6 dollars for shoes, and then paid 12.50 dollars per game. That means the total cost is given as;

`\begin{gathered} \text{Cost}=6+12.5x \\ 68.50=6+12.5x \\ \text{Subtract 6 from both sides} \\ 62.5=12.5x \\ \text{Divide both sides by 12.5} \\ x=5 \end{gathered}`

That means you played just 5 games
