Answer:
They can make 9000 crayons in 15 minutes.
Explanation:
Figure out the ratio:
![(2400)/(4)](https://img.qammunity.org/2021/formulas/mathematics/high-school/miyoiji2yfkjj98xmr2wzgx7m1qky4mg69.png)
Simplify it to get the total number of crayons that they can make in one minute.
2400/4 = 600
They can make 600 crayons per minute.
Now, you should have a proportion.
![(600)/(1)](https://img.qammunity.org/2021/formulas/mathematics/high-school/goxgn3k71psopwe353gfonvto0s7atm27f.png)
Now, multiply the denominator and numerator by 15 because whatever you do to the denominator you have to do to the numerator.
You should now have your answer.
![(9000)/(15)](https://img.qammunity.org/2021/formulas/mathematics/high-school/q8i3xasruwscx586xx7efngtfp84wnfwmi.png)
