Question 951302
a=bank one charge; b=bank 2 charge; c=no.of checks
a=$10+$0.05c
b=$5+$0.10c
Number of checks when both cost the same:
a=b
$10+$0.05c=$5+$0.10c Subtract $5 from each side
$5+$0.05c=$0.10c Subtract $0.05c from each side
$5=$0.05c Divide each side by $0.05
100=c Both banks charge the same when the number of checks written is 100.
ANSWER: Bank A is a better deal if you write more than 100 checks per month.
