2 oranges...? If I buy 2 apples and 6 oranges, I will spend $5.60. However, if I buy 6 apples and 2 oranges, I will spend $4.80. How much does one orange cost?

A. $0.55
B. $0.70
C. $0.75
D. $0.60
 
1. 2a + 6o = 560
2. 6a + 2o = 480

3. multiply line 1 by 3 = 6a + 18o = 1680

subtract line 2 from line 3

6a + 18o = 1680
-(6a + 2o =480)
----------------------------
16o = 1200

o = 75

One orange = 75 cents
