Saleem has $20. A fish tank that he wants to buy costs $140. He earns $23 per day at a restaurant. Saleem wants to know how many days he has to work to have at least enough money to buy the tank. What is an inequality statement that represents this situation?

Since he can't work a fraction of a day, he'll have to work at least 6 days to have enough money for the tank. The inequality hat represents his situation is 23*x + 20 >=140.

Step-by-step explanation:

In order to create an inequality to this problem we first need to take the initial amount he has and sum it with the days he has to work "x" multiplied by the amount he earns each day. We then have:

saleem money = 20 + 23*x

Since he wants to buy a $140 fish tank he needs to work until his money is greater or equal than this amount. So we have:

23*x + 20 > = 140

23*x > = 140 - 20

23*x > = 120

x > = 120/23

x > = 5.22

Since he can't work a fraction of a day, he'll have to work at least 6 days to have enough money for the tank. The inequality hat represents his situation is 23*x + 20 >=140.
