Answer:
The system of inequalities representing the situation above is given as:
Number of ink drawings x ≥ 0
Number of water colors ≥ 0
Number of preparation time: 0.3x + 0.5y ≤ 120
Number of packaging time: 0.2x + 0.2y ≤ 60
Explanation:
They volunteered to spend:
Number of hours for preparation = 120
Number of hours for packaging = 60
Number of hours to prepare ink drawing = 0.3
Number of hours to prepare water colour = 0.5
Number of hours it takes to package each card = 0.2
x = number of ink drawings
y = number rod water colour
The system of inequalities representing the situation above is given as:
Number of ink drawings x ≥ 0
Number of water colors ≥ 0
Number of preparation time: 0.3x + 0.5y ≤ 120
Number of packaging time: 0.2x + 0.2y ≤ 60
Option d is the correct option
