Amachine fills 80 containers of cookies in 20 minutes. at the same rate, how many containers of cookies could the machine fill in 8 hours? a) 240 b) 960 c) 1,640 d) 1,920

D) 1, 920

Step-by-step explanation:

The machine fills 80 container/20 minutes which means 4 container/1 minutes

To find the answer convert 8 hours to minutes then multiply it by 4/1.

1 hour = 60 minutes

4/1 × 8 (60)

4/1 × 480=1920

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
