Answer:
cosA = 
Step-by-step explanation:
cosA =
=
=
= 
5000(1+.07)^2
5000(1.07)^2
5000(1.14)
5,700
Your final answer should be 5,700$. If you wanna double check you would use the equation fv=bv(1+r/m)^mt
Quart because it's bigger than a pint and a quart is the closest to a gallon
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!
