A financial model has been constructed to predict the total profits of a company within the next month. The relationship is given as y = x4 - 3, where y is the amount of profit and x is the number of days. When will the company start to gain money (as in y is greater than 0) ?

The company will start to gain money when the number of days (x) is greater than 3/4

Step-by-step explanation:

To find when the company start to gain money we should solve this inequality:

We need that y (profits) >0 and also we know that the relationship between profits and amount of days is: y=4x-3, then,

4x-3>0

4x>3

x>3/4

When the number of days is greater than 3/4, the company will start to gain money.
