Answer:
100 soccer balls and 50 cork balls must be produced
Step-by-step explanation:
Let the number of soccer ball = p and number of cork ball = q
Production hours of p = 3 hours
Production hours of q = 4 hours
Then the production time equation would be:
3p + 4q ≤500
The number of the balls must be at least 150
p + q ≥150
x ≥ 0 y ≥ 0
Minimum production r = 9p + 7q
Therefore 100 soccer balls and 50 cork balls must be produced
3x + 2 > 2
3x > 2 - 2
3x > 0
x > 0
3x < = 6
x < = 6
0 < x < = 6
