`\pm0.05\text{ dollars}`

Therefore, the coach budget should be between,

`\begin{gathered} \text{for }+0.05\text{ dollars,} \\ =1.5+0.05=1.55\text{ dollars and,} \\ \text{for -0.05 dollars,} \\ =1.5-0.05=1.45\text{ dollars} \end{gathered}`

Hence, the budget of the coach should be between $1.45 and $1.55.
