Answer:
8.57 hours
Step-by-step explanation:
The cost of each host can be expressed as follows:
Host A: 60+13.25x
Host B: 75+11.50x
x is the number of hours
To find when the two host will charge the same amount you have to equate the expressions and solve for x:
60+13.25x= 75+11.50x
13.25x-11.50x= 75-60
1.75x= 15
x=15/1.75
x=8.57
The two hosts charge the same amount after 8.57 hours
Host A: 60+13.25h
Host B: 75+11.5h
60+13.25h =75+11.25h
subtract 11.25h from each side
60+2h = 75
subtract 60 from each side
2h = 15
divide by 2
h = 7.5
at 7.5 hours the two hosts will charge the same

Answer:
x = $3, or x = $11
Step-by-step explanation:
The equation given is 
where
- P(x) is the profit, and
- x is the app price
<u>We want app prices (x's) when profit (P(x)) is 0, so plugging in into the equation:</u>
<em>It means (x-3) = 0 OR (x-11) = 0</em>
So, x = 3, or 11
