4. Linear Functions
Sign In
The cost of service c for m months is equal to the monthly rate multiplied by m plus the installation fee.
Substitute the number of months into the function from Part A.
On this coordinate plane, the horizontal axis represents the numbers of months and the vertical axis represents the cost of service.
The first coordinate of a point represents the number of months of service and the second coordinate represents the cost.
c(m)=35.95m+50
| Months m | 35.95m+50 | Cost of service c(m) |
|---|---|---|
| 1 | 35.95(1)+50 | 85.95 |
| 2 | 35.95(2)+50 | 121.90 |
| 3 | 35.95(3)+50 | 157.85 |
| 4 | 35.95(4)+50 | 193.80 |
| 5 | 35.95(5)+50 | 229.75 |
See solution.
