Answer:
98 or 105
Step-by-step explanation:
A) Lets write our equations.
22x + 100 = 25x + 70
Now lets solve step-by-step.
Apply the inverse operation 22x + 100 = 25x + 70
-22x -22x
25x - 22x = 3x
3x + 70 = 100
-70 - 70 We subtract 70 from both sides because (inverse operation)
3x = 30
3x/3 = 30/3
x = 30/3
x= 10
B) We need to find which one is the most cheap.
Lets pick an integer to replace x.
22x + 100 = 25x + 70
Lets choose '2'
22(2) + 100 = 25(2) + 70
44 + 100
50 + 70
144
120
The first one : Country Carpets charges $144 , while at the same rate, City carpets charges 120.
So, obviously, City Carpets is cheaper than that other one, so he would most likely choose that one.
