Astore sells almonds for $7 per pound, cashews for $10 per pound, and walnuts for $12 per pound. a customer buys 12 pounds of mixed nuts consisting of almonds, cashews, and walnuts for $118. the customer buys 2 more pounds of walnuts than cashews. the matrix below represents this situation.

Step-by-step explanation:

Let the customer buys, x pounds of almonds, y pounds of cashews and z pounds of walnuts. Since he buys 12 pounds of mixed nuts

Then since total weight he purchases is 12, we get

x+y+z = 12...i

Next is rate of each nut multiplied by pounds and added give the total cost.

Hence we have

7x+10y+12z=118 ... ii

A customer buys 2 more pounds of walnuts than cashews.

z=y+2 or

y-z=-2 ....iii

This can be written in matrix form as

Ax =B

21
