A membership at gym A costs $50 for 5 months. A membership at gym B down the street costs $40 for 3 months. What is the value of K for the cheaper membership?

To find the value of K, we need to compare the cost of the memberships at gym A and gym B.

The cost of the membership at gym A is $50 for 5 months.
The cost of the membership at gym B is $40 for 3 months.

To compare the two membership costs, we can set up a ratio:

Cost of gym A membership / Cost of gym B membership = K

$50 / $40 = K

Simplifying the ratio, we get:

5/4 = K

Therefore, the value of K for the cheaper membership is 5/4.
