Answer 1

Price for company A:
p(A) = 10 + 5*h

Price for company B:
p(B) = 7*h

,where h is the hours.

To find the hours after which the prices for both are going to be the same, we set the price for A equal to the price of B and calculate h.

10 + 5*h = 7*h <=>

2*h = 10 <=>

h = 10/2 <=>

h = 5 hours
