<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the total cost for x number of service calls in a year. Hence:
y = 39x + 349200
For 200 service call, in a year, x = 200 * 12 = 2400
y = 39(2400) + 349200 = $442800
Average cost = $442800 / 2400 = 184.5
The average cost per cleaning service call charge by the company is $184.5.

2x + 5 = 15 - (-49) x 5
combine like terms
2x + 5 = 320
subtract 5 from each side
2x = 315
divide by 2 on each side
x = 157.5
