Answer:
B: 11 minutes.
Step-by-step explanation:
So, we know that the machine prints at a constant rate.
After 3 minutes, the machine prints 108 posters.
So, let’s find the <em>unit rate. </em>We will divide the output over the input. So:
So, the unit rate of the machine is 36 posters per minute.
We can write an equation. If t represent the number of minutes and p represent the amount of posters, then:
Gives the amount of posters p and t minutes.
We want to know how long it will take Jeffrey to make 396 posters.
So, we can substitute 396 for p and solve for t. Hence:
Divide both sides by 36:
Therefore, it will take Jeffrey 11 minutes to make 396 posters.

Answer:
6.)D 8.)C 9.)C
Step-by-step explanation:
6.)2 3/4 feet is 33 inches. Then devide 156 by 33 then you get 4.7... from this caleb can only make 4 peices of wood.
8.)First make a proportion 0.125/0.75 to x/1. Then devide 1 by 0.75 and use that number to multipy it by 0.125 and get 0.167. Then devide all the answer choices to see that 1/6 = 0.167
9.) 10/18=0.56 and 45/81=0.56 equal proportion
