Final answer:
Jeremiah should choose Macho Human, as it is more cost-effective in the long term, costing $10 for the first month and then $7 per month thereafter, compared to Flexible Fam's consistent $10 per month fee.
Step-by-step explanation:
The question is asking which gym membership, Flexible Fam or Macho Human, is more cost-effective for Jeremiah. To determine this, we need to compare the cost of each gym over a specific period. Flexible Fam has no sign-up fee and charges $10 per month. In contrast, Macho Human has a $7 monthly fee but also a one-time $3 sign-up fee.
Let's calculate the total cost for each gym over the first month. The cost of Flexible Fam would be $10 (since there is no sign-up fee). On the other hand, Macho Human would cost $10 as well ($7 monthly fee + $3 sign-up fee).
However, if we consider multiple months, Macho Human becomes more cost-effective. For example, over two months, Flexible Fam would cost $20 ($10/month x 2 months), whereas Macho Human would cost $17 ($7/month x 2 months + $3 sign-up fee).
Therefore, the answer would be option b) Macho Human, as it would be the more cost-effective choice overall after the first month.
