Answer:
Step-by-step explanation:
We have been given that checking account earnings at Long's Bank are expressed by the equation . The earnings at Fellow's Bank are modeled by . In both cases x is the number of checks written.
To find the number of checks that will generate more earnings at Long's bank then Fellow's Bank, we will set an inequality as:
Now let us solve for x.
Now let us divide both sides of our inequality by -0.04. Since dividing by a negative number swaps sign of inequality, so our inequality will be:
Since the number of checks needs to be integer, so number of checks will be:
Therefore, the number of checks between 0 to 42 checks will generate more earnings income at Long's Bank than Fellow's Bank.
