Lydia buys 3 apples and 2 pears from a fruit stand and spends $3.85. The next week she goes back and buys 4 apples and 1 pear and spends $3.80 Which system of equations can be used to find the cost per apple, a, and the cost per pear,
AO S 3a+2p= 3.80
4a + p - 3.85
BO S 3a + 2p 3.85
4a + p - 3.80
CO 3a + 4a = 7.65
2p+ p = 7.65
DO 3a - 2p 3.85
14a - p= 3.80
