Ed decides to include more fruit in his diet. He goes to the grocery store over the weekend and buys 6 apples, 6 oranges, and 6
avocados. The total cost is $19.50. Ed finishes the apples very quickly, and has some leftover avocado. The following weekend he buys 12 apples, 2 oranges, and 1 avocado. This time he pays just $9.50.
The following week, Ed reads an article on the benefits of avocado, so over the weekend he buys 5 avocados along with 2 apples and 4 oranges. His total this time is $14.
Assume that Ed pays a unit price rather than a price per pound for the apples, oranges, and avocados.
Write the three equations that give the total amount Ed paid each week for fruit.
Let an apple be x,and oranges be y,and avocados be z. So in first week the equation would be 6x+6y+6z=19.50, x+y+z=3.25 Similarly next equation would be 12x+2y+z=9.50 Third equation 2x+4y+5z
