Problem on Linear equations

Anny, Betti and Karol went to their local produce store to bpought some fruit. Anny bought 1 pound of apples and 2 pounds of bananas and paid $2.11.  Betti bought 2 pounds of apples and 1 pound of grapes and paid $4.06.  Karol bought 1 pound of bananas and 2 pounds of grapes and paid $4.45.

(a) Let x = price of a pound of apples,  and y = price of a pound of bananas and z = price of a pound of grapes.  Write out three linear equations symbolizing the purchases of Anny, Betti and Karol.

(b) Write down the augmented matrix for your system of three linear equations of part (a).

(c) Employ elementary row operations to reduce the row augmented matrix of part (b) to a reduced row-echelon matrix.

(d) Determine the price per pound for each of 3 fruits?
