You have $25 to spend picking 21 pounds of three different types of apples at an orchard. The Empire apples cost $1.40 per pound, the Red Delicious apples cost $1.10 per pound and the Golden Delicious apples cost $1.30 per pounds. You want twice as many Red Delicious apples as the other two combined. How many of each type of apple should you buy?
If you could answer this question by showing a matrix equation that would be great. If you don’t know how to do that, any equation would be great and I can make it into a matrix. Please include the answer. I’ll give 10 points to whoever answers correctly so please help! I’m freaking out here and your my only hope!
