Kent invested $5000 in a retirement plan. He allocated x dollars of the money to a bond account that earns 4% interest per yr and the rest to a traditional account that earns 5% interest per yr.

Write an expression that represents the amount of money invested in the traditional account.

To write an expression that represents the amount of money invested in the traditional account, we need to consider that Kent allocated x dollars to the bond account, and the rest of the money (which is $5000 - x) was invested in the traditional account.

Therefore, the expression that represents the amount of money invested in the traditional account is:

Traditional Account = $5000 - x
