At a local market, the price of each apple is the same, and the price of each banana is the same. On Monday, Emily bought 7 apples and 4 bananas for a total of $15. On Tuesday, David bought 3 apples and 8 bananas for a total of $17. Let represent the price, in dollars, of each apple and represent the price, in dollars, of each banana. Which system of linear equations represents this situation?
7a + 3b = 15
4a + 8b = 17
7a + 4b = 15
3a + 8b = 17
7a + 4b = 17
3a + 8b = 15
4a + 7b = 15
8a + 3b = 17
