One real zero solution, as is 0, and he must take 12 trips.
Step-by-step explanation:
His amount of funds is given by:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that , given by the following formulas:
How many trips he must take to spend all of his remaining business travel funds?
x trips, and x is found when f(x) = 0. So
Quadratic equation with
So
One real zero solution, as is 0, and he must take 12 trips.
