Answer:
1920 containers of cookies could be filled by the machine in 8 hours.
Step-by-step explanation:
To solve this problem, we will follow the steps below;
First, lets change 8 hours to minutes
8 hours = 8 × 60 =480 minutes
Now using proportion,
Let x be the number of containers of cookies the machine can fill in 8 hours
20 minutes = 80 containers
480 minutes = x
cross-multiply
20×x = 480×80
20 x =38400
Divide both-side of the equation by 20
[tex]\frac{20X}{20}[/tex] = [tex]\frac{38400}{20}[/tex]
(At the left-hand side of the equation 20 will cancel-out 20 leaving us with x while at the right-hand side of the equation 28400 will be divided by 20)
x= 1920 containers.
Therefore, 1920 containers of cookies could be filled by the machine in 8 hours.
