A business shipped 114 packages one day. Customers are charged $4.50 for each standard-delivery package and $7.50 for each express-delivery package. Total shipping charges for the day were $591.00. How many of each kind of package were shipped?
Answer provided by our tutors
let
s = the number of standard-delivery packages
e = the number of express-delivery packages
a business shipped 114 packages one day
s + e = 114
total shipping charges for the day were $591.00
shipping charge for s standard-delivery packages + shipping charge for e express-delivery packages = total shipping charges
4.50s + 7.50e = 591
by solving the system of equations
s + e = 114
4.50s + 7.50e = 591
we find
s = 88 packages
e = 26 packages
