Answer:
No, Vicky should not switch.
Explanation:
Vicky's checking account charges a monthly service fee = $12.25
Account also charges per-check fee = $0.26
Vicky writes checks per month = 16
His total monthly charges = 12.25+( 16 ×0.26 )
= 12.25 + 4.16
= $16.41
Another account that charges a $16.50 monthly service fee and no per-check fee.
Comparison between account = 16.50 > 16.41
So Vicky should not switch to another account because it charges more than her current account.
