David sold two video games for $6 and three video games for $8. he used the money to buy two new video games that cost $15 each, and still had some money left over. which equation can be used to find y, the amount of money david had left after he sold five games and bought two more? a. y = (2 × 6) + (3 × 8) − (2 × 15) b. y = (2 × 15) − (2 × 6) + (3 × 8) c. y = (2 × 3 + 14) − (2 × 15) d. y = (5 × 14) − (2 × 15)

Can someone answer these problems for me
