Question

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 â€" r) = 5 1. 5r 2. 5(5 â€" r) = 10. 50 1. 5r 2. 5(5 â€" r) = 5.

Answer 1

The equation that Jeremy can  use to determine the amount of raisins in the trail mix will be C. 1.5r + 2.5(5 - r) = 10.50

Let r = the amount of raisins

Let p = the amount of peanuts

The equation will be:

r + p = 5 ...... i

1.5r + 2.5p = 10.50

From equation i, p = 5 - r .. iii

Equation iii will be substituted into ii

1.5r + 2.5p = 10.50

1.5r + 2.5(5 - r) = 10.50

In conclusion, the correct option is C.
