Answer 1

Answer:

For 0 hours = $40

For 1 hours = $75

For 2 hours = $110

For 3 hours = $145

For 4 hours = $180

For 5 hours = $215

Step-by-step 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:

$C=35n+40$

$C=(35\times 0)+40$

$C=0+40$

$C=40$

Therefore for 0 hours Amy charge $40.

For 1 hours:

$C=35n+40$

$C=(35\times 1)+40$

$C=35+40$

$C=75$

Therefore for 1 hours Amy charge $75.

For 2 hours:

$C=35n+40$

$C=(35\times 2)+40$

$C=70+40$

$C=110$

Therefore for 2 hours Amy charge $110.

For 3 hours:

$C=35n+40$

$C=(35\times 3)+40$

$C=105+40$

$C=145$

Therefore for 3 hours Amy charge $145.

For 4 hours:

$C=35n+40$

$C=(35\times 4)+40$

$C=140+40$

$C=180$

Therefore for 4 hours Amy charge $180.

For 5 hours:

$C=35n+40$

$C=(35\times 5)+40$

$C=175+40$

$C=215$

Therefore for 5 hours Amy charge $215.
