An air-conditioning and heating company has a fixed monthly cost of

Question

$5000
. Furthermore, each service call costs the company
$20
.

(a) Write a linear equation to compute the total cost,
y
, for
1
month if
x
service calls are made.
The linear equation in slope-intercept form is
.

Answer 1

The total cost y for x service calls can be calculated as follows:

y = $5000 (fixed monthly cost) + $20 (cost per service call) * x (number of service calls)

Therefore, the linear equation in slope-intercept form is:
y = 20x + 5000
