Valerie Watkins is preparing walnut and raisin mix. Walnuts cost $2 per pound and raisins cost $3 per pound. She wants to spend
exactly $22.50 for the walnut and raisins, and buy a total of 10 pounds. Solve the linear system where x represents the number of pounds of walnuts and y represents the pounds of raisins. How many pounds of walnuts will she need to buy? X + y = 10 2x + 3y = 22.5
