Question

Ice cream cones $1.80 and sundaes cost $3.30. One day receipts for a total of 148 cones and sundaes were 360.90. How many cones were sold? How many sundaes?

Answer 1

85 cones and 63 sundaes were sold

Explanation:

Given:

Cost of cones = $1.8

Cost of sundaes = $3.3

Let the number of cones be c

Let the number of sundaes be s

According to the question:

c + s = 148                            - 1

1.8c + 3.3s = 360.9              - 2

Multiplying equation 1 with 1.8 we get:

1.8c + 1.8s = 266.4                - 3

Solving equation 2 and 3 we get:

1.8c + 3.3s = 360.9

1.8c + 1.8s = 266.4

__________________

1.5s = 94.5

s = 63

Putting the value of s = 63 in equation 1

c + 63 = 148

c = 85

Therefore, 85 cones and 63 sundaes were sold
