Problema Solution
At a store, ice cream cones cost $1.80 and sundaes cost $3.30. One day a total of 212 cones and sundaes were sold, and the receipts totaled $531.60. How many cones were sold?
Answer provided by our tutors
let
x = the number of ice cream cones
y = the number of sundaes
One day a total of 212 cones and sundaes were sold:
x + y = 212
and the receipts totaled $531.60:
1.80x + 3.30y = 531.60
by solving the system of equations:
x + y = 212
1.80x + 3.30y = 531.60
we find:
x = 112 cones
y = 100 sundaes
