Answer:

For the length of time less than 6 hours cost less to hire Hanks movers

Step-by-step explanation:

Let

x -----> the time in hours

y ----> the total cost in dollars

we know that

Acme movers

[tex]y=30x+150[/tex] ----> equation A

Hanks movers

[tex]y=55x[/tex] ----> equation B

Equate equation A and equation B and solve for x

[tex]55x=30x+150[/tex]

[tex]55x-30x=150[/tex]

[tex]25x=150[/tex]

[tex]x=6\ hours[/tex]

That means-----> For x= 6 hours The cost in both companies is the same

Verify

For x=6 hours

Acme movers

[tex]y=30(6)+150=\$330[/tex]

Hanks movers

[tex]y=55(6)=\$330[/tex]

If x < 6 hours ----> It cost less to hire Hanks movers

If x > 6 hours ----> It cost less to hire Acme movers

therefore

For the length of time less than 6 hours cost less to hire Hanks movers
