7.14 mile per hour is how fast she ran
Basically its 250 + 16x = 210 + 18x where x = the number of hours doing the job.
Solving, we get 40 = 2x, x =20
The jobs has to be 20 hours long in order for their two painting jobs to be equally priced.
Hope this helped!
(f o g o h)(x) = f { g [ h(x) ] }
Which means: apply first function h, then apply function g to the result, and finally apply function f to the new result.
h(25) = √25 = 5
g(5) = 5 - 3 = 2
f(2) = 3(2) = 6.
Answer: 6
