Need help for this question

Answer 1

For 0 hours = $40

For 1 hours = $75

For 2 hours = $110

For 3 hours = $145

For 4 hours = $180

For 5 hours = $215

Explanation:

Given equation is:-
`C=35n+40`

where, C=Cost in dollars, n=hours.

Now, Amy charge $40 for service call and $35 for per hour service.

So,

For 0 hours:

`C=35n+40`

`C=(35* 0)+40`

`C=0+40`

`C=40`

Therefore for 0 hours Amy charge $40.

For 1 hours:

`C=35n+40`

`C=(35* 1)+40`

`C=35+40`

`C=75`

Therefore for 1 hours Amy charge $75.

For 2 hours:

`C=35n+40`

`C=(35* 2)+40`

`C=70+40`

`C=110`

Therefore for 2 hours Amy charge $110.

For 3 hours:

`C=35n+40`

`C=(35* 3)+40`

`C=105+40`

`C=145`

Therefore for 3 hours Amy charge $145.

For 4 hours:

`C=35n+40`

`C=(35* 4)+40`

`C=140+40`

`C=180`

Therefore for 4 hours Amy charge $180.

For 5 hours:

`C=35n+40`

`C=(35* 5)+40`

`C=175+40`

`C=215`

Therefore for 5 hours Amy charge $215.
