Apples sell for $1.90 per pound, and bananas sell for $0.75 per pound. Troy bought some apples and some bananas. Together they weighed 3.8 pounds, and cost $5.84. Let p represent the number of pounds of apples Troy purchased. Which equation represents the problem described here? A. 1.9p + 0.75 = 3.8 B. 1.15p + 2.85 = 3.8 C. 1.15p + 2.85 = 5.84 D. –1.15p + 2.85 = 5.84

You would first develop a system of two equations in two variables. x count pounds apples y count pounds bananas x+y=3.8 accounts for pounds. 1.9x+0.75y=5.84 accounts for cost. Use the pounds equation to substitute either for x or for y, into the cost equation, simplify, and see what matches.
