A gym membership costs $25 to join and $14 each month. Write and use an algebraic expression to find the cost of the gym membership for 6 months

The algebraic expression to find the total cost of the gym membership for 6 months is:

Total cost = 25 + 14(6) = 25 + 84 = $<<25+14*6=109>>109. Answer: \boxed{109}.

To find the cost of the gym membership for 6 months, we need to add the joining fee of $25 to the monthly cost of $14 multiplied by the number of months. Let's write an algebraic expression to represent this:

Cost of gym membership for 6 months = $25 + ($14 x 6)

Simplifying the expression:

Cost of gym membership for 6 months = $25 + $84

Cost of gym membership for 6 months = $109

Therefore, the cost of the gym membership for 6 months is $109.
