andrey2020 [161]

Answer:

b. 300x1 + 125x2 < = 4,000

Step-by-step explanation:

Maximum of 4,000 hours

T \leq 4000

300 ping-pong balls (x1) or 125 wiffle balls (x2) can be produced per hour of labor

The total amount of labor is:

T = 300x1 + 125x2

Uniting the two equations:

T \leq 4000

300x1 + 125x2 \leq 4000

And thus the correct answer is given by option b.
