Answer:

2 hours

Step-by-step explanation:

Given

[tex]Contractor: 81x + 108[/tex]

[tex]Electronic\ Store: 103x + 64[/tex]

Required

Determine the hours when the charges are the same

To do this, we simply equate both expressions:

[tex]Contractor = Electronic\ Store[/tex]

[tex]81x + 108 = 103x + 64[/tex]

Collect Like Terms

[tex]81x - 103x = 64 - 108[/tex]

[tex]-22x = -44[/tex]

Divide both sides by -22

[tex]x =2[/tex]
