Question

cool treats sold 60 ice cream cones. Single dip cones sold for $2.50 each double dip cones sold for $4.15 each. In all, $179.70 was taken in for the cones. How many of each type of cone were sold?

Answer 1

Let s = number of single-dip cones

d = number of double-dip cones.

s + d = 60

2.50s + 4.15d = 179.70

2.50s + 4.15(60 - s) = 179.70

2.50s + 249 - 4.15s = 179.70

1.65s = 69.30

s = 42, d = 18

42 single-dip cones, 18 double-dip cones
