A local Computer City sells batteries ($3) and small boxes of pens ($4). In August, total sales were $912. Customers bought 4 times as many batteries as boxes of pens. How many of each did Computer City sell?
-----
Quantity Eq:: b = 4p
Value Eq::::: 3b+4p = 912
---------
Substitute for "b" and solve for "p"::
3(4p)+4p = 912
16p = 912
------
p = 57 (boxes of pens)
b = 4p = 228 (boxes of batteries)
