n=21-10
n=11
Answer:
Number of ice cream cones = 65
Number of sundaes = 49
Step-by-step explanation:
Let
x = number of ice cream cones
y = number of sundaes
x + y = 114 (1)
2x + 3.5y = 301.50 (2)
From (1)
x = 114 - y
Substitute into (2)
2x + 3.5y = 301.50 (2)
2(114 - y) + 3.5y = 301.50
228 - 2y + 3.5y = 301.50
- 2y + 3.5y = 301.50 - 228
1.5y = 73.50
y = 73.50/1.5
y = 49
Substitute y = 49 into (1)
x + y = 114 (1)
x + 49 = 114
x = 114 - 49
x = 65
Number of ice cream cones = 65
Number of sundaes = 49
