Question

To join Karate Klub, David must pay a monthly fee of $25 and an initial fee of $200. If he
chooses Kool Karate, he must pay an initial fee of only $100 but $35/month?

Answer 1

Let's represent the total cost to join Karate Klub as K, and the total cost to join Kool Karate as KK.

For Karate Klub:
K = $25 (monthly fee) + $200 (initial fee)

For Kool Karate:
KK = $35 (monthly fee) + $100 (initial fee)

Now, we can compare the two options to determine when the costs are equal:

25 + 200 = 35 + 100

225 = 135

This equation is not true, which means the costs are not equal. Therefore, there is no solution to this equation and joining Karate Klub is more expensive in the long run.
