To answer this item, we let the number of small, medium, and large popcorns sold be equal to x, y, and z such that the total amount that can be obtained from the sales is,
2x + 3y + 4z = total sales
If the 9p is the total number of popcorns sold, the equation is,
x + y + z = 9p
Answer:
$140.90
Step-by-step explanation:
**22% = 0.22**
X = 109.90 / (1 - 0.22)
X = 109.90 / 0.78
X = 140.90
D=100:
g=12-1/25(100)
g=12-4
g=8, d=100
d=200:
g =12-1/25(200)
g=12-8
g=4, d=200
d=300:
g =12-1/25(300)
g=12- 12
g=0, d=300
