Assistance needed.
Total=onetime+numbermonths*45
solve for number months
To find out how long your friend has been a member of the gym, we can subtract the one-time fee from the total amount paid, and then divide the remaining amount by the monthly fee.
Let's break it down step by step:
1. Subtract the one-time fee ($75) from the total amount paid ($345):
Total amount paid - One-time fee = Remaining amount paid
$345 - $75 = $270
2. Divide the remaining amount paid ($270) by the monthly fee ($45):
Remaining amount paid / Monthly fee = Number of months
$270 / $45 = 6 months
Therefore, your friend has been a member of the gym for 6 months.
