The number (b) of bolts a machine can make varies directly as the time (t) it operates. it can make 6,000 bolts in 2 hours. how many can it make in 5 hours?

For this case we have a function of the form:

b = k * t

Where,

k: proportionality constant.

For this case:

k = 6000/2

k = 3000

Substituting values:

b = 3000 * t

For t = 5 we have:

b = 3000 * 5

b = 15000

Answer:

it can make in 15000 bolts in 5 hours
