Answer 1

Answer: According to the information the following equation can be constructed for the unknown tire price x, the equation is:

`(1.1)x+60<593.50\rightarrow(1)`

The solution to the equation (1) is as follows:

`\begin{gathered} (1.1)x+60\lt593.50 \\ \\ (1.1)x\lt593.50-60 \\ \\ (1.1)x\lt533.5 \\ \\ x<(533.5)/(1.1) \\ \\ x<\$485 \\ \\ \text{ The answer is \lparen a\rparen} \end{gathered}`
