(1) Eric works at the deli on weekends to earn extra money. He makes \( \$ 10 \) per hour making sandwiches, and \( \$ 14 \) per hour delivering orders. Eric puts half of his total earnings in a savings account for college. He wants to know how much he saves each week. 4) Which expression represents the total amount of money Eric saves for working \( s \) hours making sandwiches and \( d \) hours delivering orders? \[ 10 s+14 d \quad 10 s+14 d \div \frac{1}{2}\left[\frac{1}{2}(10 s+14 d) \quad \frac{1}{2} \cdot 10 s+14 d\right. \]
