Think of a real-life situation that can be translated to a polynomial function and solve the problem.
:
you have to earn at least $3000 this summer, to be able to return to college:
:
You found a construction job that will let you take home $120 per day.
:
The job site is 50 miles from your home. You must drive 100 mi every day.
:
The car you own costs 25 cents a mile to operate (It's an old one).
:
You bring your own lunch (using your parents food) so no expense there.
:
How many days will you have to work to have $3000 at the end of the summer.
:
Let x = number of days worked, f(x) = 3000
:
f(x) = 120x - x(.25*100)
:
Wages - car expense = required amt
120x - x(.25*100) = 3000
120x - x(25) = 3000
120x - 25x = 3000
95x = 3000
x = 3000/95
x = 31.58 days, so let's say you must work 32 days to reach your goal goal
:
:
Check it using 32 days
120(32) - 32(25) =
3840 - 800 = $3040.00
:
Actually this is a real life situation that occurred not too long ago
