Answer

10 hours

Explanation

Step one:

given information

Company A

charges $45 per hour and a $150 equipment fee.

Let A represent the amount Company A would charge for  t hours

So, the expression for the total is

A= 45t+1501

Company B

charges $35 per hour and a $200 equipment fee.

Let B represent the amount Company B would charge for  t hours

So, the expression for the total is

B= 35t+2002

Step two:

equating the two equations above

A=B

45t+150=35t+200

collect like terms

45t-35t= 200-150

5t=50

divide both sides by 5

t=50/5

t=10
