After 19 months, the cost will be same for both memberships.
Step-by-step explanation:
Given,
Sign up fee at Power Plus = $22.00
Per month fee = $34.14
Let,
x be the number of months.
P(x) = 34.14x + 22
Sign up fee at Heavy Hulk = $34.50
As they have cut the cost into half.
Sign up fee = 
Per month fee = $34.39
H(x) = 34.39 + 17.25
For same cost ;
P(x) = H(x)

Dividing both sides by 0.25

After 19 months, the cost will be same for both memberships.
