Well do you have a guess?

We would need to find the boxes the machine can make in one minute...So we would divide the two....

$\huge\bf{\frac{18}{5} = unit~rate}$

@sissyedgar No. I'm really lost on this subject :(

563blackghost · Answer

This has to deal with unit rate....what do you know of unit rate?

563blackghost · Answer

I provided the fraction in order to find the unit rate of the number of boxes per minute all you need to do is divide it to find it....@Zaynwich

So 72?

sissyedgar · Answer

The equation above is completely correct...
$$\frac{ 18 }{ 5 }$$ 
When you put that into your calculator (which is just 18 divided by 5) what do you get?
