The number of plastic straws produced by a machine varies directly as the amount of time the machine is operating. If the machine produces 20,00 straws in 8 hours how many straws can it produce in 50 hours?

Answer 1

To solve this problem, we can set up a proportion:

Let x be the number of straws produced in 50 hours.

20,000 straws / 8 hours = x straws / 50 hours

20,000/8 = x/50
2,500 = x/50

Multiplying both sides by 50:
2,500 * 50 = x
125,000 = x

Therefore, the machine can produce 125,000 straws in 50 hours.
