Solve a fixed multi-step context model

Problem

A plumber charges $\$8$ travel plus $4~\text{visits}$, each with $x~\text{dollars}~\text{labor}$ and $\$3$ supplies, for $\$60$ total. Complete and solve: $8~+~4(x~+~3)~=~60$; $x~=~\text{\_\_\_}$.

8 + 4(x + 3) = 60; x = $13

8 + 4(x + 3) = 60; x = $10 labor per visit

4(8 + x) + 3 = 60; x = $6.25

8 + 4x + 3 = 60; x = $12.25
