According to the profit equations given, it is found that since the number of days has to be a positive value, hence the viable answer is that they earn the same profit after 3 days, while the nonviable answer is -4.
<h3>What are the profit equations?</h3>
For the first friend, it is:
For the second, it is:
.
The system we solve to find when they earn the same profit is given by:
Which is a quadratic equation with coefficients a = 1, b = 1, c = -12. Hence:
The number of days has to be a positive value, hence the viable answer is that they earn the same profit after 3 days, while the nonviable answer is -4.
