Answer:
here
Step-by-step explanation:
use Gauth Math
source given:
$370 for a membership
cost to join: $50
370 - 50 = 320
Now, 20 a month
A month comprises of 4 weeks
A year comprises of 12 months
so,
12 X 20 = 240
320 - 240 = $120
remaining, $120
20 = 1 month
120 = 6 months
18 months???
I am not sure if this is correct, but hope it helps.
