Question

Which is a better buy—100 sheets of binder paper at $2.50, or 150 sheets at $3.50?

Answer 1

150 sheets is the better buy.

Explanation:

Cost of each sheet when buying 100 = $2.50 / 100 = $0.0250'

If you buy 150 cost per sheet = $3.50 / 150 = $0.0233.....

So buying 150 sheets is the better buy.
