Problema Solution
a candy store at the mall sells gummy flies for $5.25 per pound and dew drops for $6.50 per pound. If they sell four times as many pounds of dew drops as gummy flies, and take in $906.25, how many pounds of dew drops did they sell?
Answer provided by our tutors
let
g = lbs of gummy flies
d = lbs of dew drops
they sell four times as many pounds of dew drops as gummy flies:
d = 4g
and take in $906.25:
5.25g + 6.50d = 906.25
by solving the system of equations:
d = 4g
5.25g + 6.50d = 906.25
we find:
g = 29 lbs
d = 116 lbs
