Based on your comment I assume you want to find 7,533 subtracted by 7,200. To estimate this, round 7,533 to the hundreds place, so 7,533 becomes 7,500.
7,500 - 7,200 = 300, using mental math.
Equation for company a: y=20x+8
Equation for company b: y=24x+4
Company A would be cheaper for 5 loads of laundry, because it is $108 dollars opposed to $124 which is what company b would charge for 5 loads.
$32 dollars is saved by using the services of company A instead of company B to clean 9 loads of laundry.
Would the common factor be 1?
edit
the least common is 1 and the most common is 2
