acme movers charges $150 plus $30 per hour to move household goods across town. hanks movers charges $55 per hour. for what leng
Fittoniya [83]

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

<em>Acme movers</em>

y=30x+150 ----> equation A

<em>Hanks movers</em>

y=55x ----> equation B

Equate equation A and equation B and solve for x

55x=30x+150

55x-30x=150

25x=150

x=6\ hours

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

<u><em>Verify</em></u>

For x=6 hours

<em>Acme movers</em>

y=30(6)+150=\$330

<em>Hanks movers</em>

y=55(6)=\$330

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
