Christine(C) and Ty(T) save quarters in a jar together. The jar had $28 in it, then Christine put in C quarters and Ty put in T quarters. Which expression can be used to represent the amount of money in the bank now?

CT + 28

0.50(C + T) + 28

0.25C + 0.25T + 28

0.25FJ + 28

The correct expression is: 0.25C + 0.25T + 28.

The expression that can be used to represent the amount of money in the bank now is: 0.25C + 0.25T + 28.

To represent the amount of money in the jar now, we need to calculate the total value of the quarters that Christine and Ty put in and then add it to the initial amount of $28.

Since a single quarter is worth $0.25, Christine putting in C quarters would contribute a value of 0.25 * C, and Ty putting in T quarters would contribute a value of 0.25 * T.

The correct expression to represent the amount of money in the jar now would be:

0.25C + 0.25T + 28
