Jeremy is making a trail mix containing raisins and peanuts. Raisins cost $1. 50 per pound. Peanuts cost $2. 50 per pound. Jeremy spends $10. 50 to make 5 pounds of trail mix. He uses the table below to organize this information. A table titled trail mix showing pounds, cost, and total. The first row shows raisins, with r, 150, and 1. 5 r. The second row shows peanuts, with 5 minus r, 2. 50, and 2. 5 left-parenthesis 5 minus r right parenthesis. The last row shows mixture, with 5, blank, and 10. 50. Which equation can jeremy use to determine the amount of raisins in the trail mix? r + 1. 50 = 1. 5r r + (5 – r) = 5 1. 5r + 2. 5(5 – r) = 10. 50 1. 5r + 2. 5(5 – r) = 5.
