Answer provided by our tutors
let
b = the number of batteries sold
p = the number of boxes of pens sold
Customers bought 5 times as many batteries as boxes of pens:
b = 5p
In August, total sales were $945
2b + 5p = 945
by solving the system of equations
b = 5p
2b + 5p = 945
we find
b = 315 batteries
p = 63 boxes of pens
