85 cones and 63 sundaes were sold
Step-by-step 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
