Answer
2 months
Work Step by Step
Club 1's cost is represented by 50+65x. Club 2's cost is represented by 90+45x. X is the number of months. Set them equal to find out when the two costs will be equal.
50+65x=90+45x (subtract 45 from both sides)
50+20x=90 (subtract 50 from both sides)
20x=40 (divide both sides by 20 to isolate the variable)
x=2
After 2 months, the costs will be equal.
