Answer:
i havent but my friend has. she still do but not as often
Step-by-step explanation:
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
4:5 is to 12:15 because 4•3=12
You have to solve for 9x first
