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.

Alessandra · Answer 1

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
