Step 1
Given the function;
[tex]\begin{gathered} C(s)=0.8s+0.29 \\ \text{where; } \\ s=amount\text{ of snow in inches} \\ C(s)=service\text{ calls} \end{gathered}[/tex]
Required; To find how many services calls Roger will have if 4.7 inches of snowfalls
Step 2
Substitute for s=4.7inches
[tex]\begin{gathered} C(4.7)=0.8(4.7)+0.29 \\ C(4.7)=4.05 \\ C(4.7)\approx4\text{ service calls to the nearest whole number} \end{gathered}[/tex]
Hence, he will receive approximately to the nearest whole number 4 service calls.
