You bought eight oranges and one grapefruit for a total of 4.60. Later that day you bought six oranges and three grapefruits for a total of 4.80. now you want to find the price of each orange and of each grapefruit. write an equation for each purchase. solve the system of equations.

x = oranges, y = grapefruits
8x + y = 4.60
6x + 3y = 4.80

Do you understand why these are the 2 equations?
Now solve them the way you were taught in class.
