Answer:
Italian style = 19,000 packages
French style = 13,000 packages
Oriental style = 53,000 packages
Explanation:
let the number of packages of Italian style = x
let the number of packages of French style = y
let the number of packages of Oriental style = z
See the attached table which summarize the problem
Using the table we can get the following system of equations:
0.4x + 0 * y + 0.2z = 18,200
0.3x + 0.5y + 0.3z = 28,100
0.3x + 0.5y + 0.5z = 38,700
Solving the 3 equations together to find x , y and z
Using the calculator
x = 19,000
y = 13,000
z = 53,000
