solving using equations is easy.
(x represents per check)
total charge(monthly)=0.05x+$6
what you got for the month was $6.90
to find the number of checks:
0.05x+$6=$6.90
-$6 -$6
0.05x =0.90
----- ----
0.05 0.05
x =18
the answer is 18 checks to get $6.90 in a month
to confirm is answer is right:
0.05x+$6
instead of x put in 18
0.05(18)+$6
0.90 +$6
=$6.90
so to get $6.90 in a month one needs to 18 checks
