Question

Luanne bought 50 stamps, some costing 37 cents and the rest costing 22 cents. She paid the postal clerk a total of $13.25 for all the stamps. How many of each type of stamp did Luanne buy?

I keep on getting 1 for the 37 stamp, which doesnt make sense.

Answer 1

H*.37+(50-H).22=13.25
H(.15)+11=13.25
H= 2.25/.15=15=expensive stamp
(50-H)=35=cheap stamp
