Final answer:
Sam saves $1,425 annually by not using the check cashing service since he now has a bank account that does not charge a fee for cashing or depositing checks.
Step-by-step explanation:
If Sam is making $28,500 per year and he was using a check cashing service that charges a 5% fee, we can calculate the amount he will save by no longer using this service. To do this, we simply need to calculate 5% of his annual paycheck:
$28,500 x 0.05 = $1,425
So, by not going to Ready Cash anymore, Sam will save $1,425 annually. Therefore, the correct answer to how much Sam will save is option a) $1,425.
