A manufacturer produces three products x, y, z which he sells in two markets.
Annual sales are indicated below:
Market Products
I. 10,000 2,000 18,000
II. 6,000 20,000 8,000
(a) If unit sale prices of x, y and z are $2.50, $1.50 and $ 1.00, respectively,
find the total revenue in each market with the help of matrix algebra.
(b) If the unit costs of the above three commodities are $2.00, $ 1.00 and
50 cents respectively. Find the gross profit.
