Jose earns $60 a day. After a few days. Jose has $240. How many days has Jose worked?

We can write this equation as 60d=b where the d represents the days he works. If he works 1 day we replace the d with a 1 and multiply 60 by 1. B would represent the balance he has after working d days. If we know he ha 240$ we can write the equation as
60d=240
We need to solve for d the number of days he worked and to do this we need to get d by itself
Divide 60 by both sides because in doing so, we will remove the 60 from d to get d alone
60d/60=240
***D=4***
Jose has worked 4 days
