A store sells apples for $0.50 each and oranges for $0.75 each. If a customer buys 4 apples and 3 oranges for a total of $3.25, write a system of equations to represent this situation.

• 0.50x + 0.75y = 3.25 x = 5 y = 2

• 0.50x + 0.75y = 3.25 x = 4 y = 3

• 0.50x + 0.75y = 3.50 x = 4 y = 3

• 0.50x + 0.75y = 3.25 x = 3 y = 4
