A recipe for 1 lb of trail mix calls for 5.7 oz of raisins. How many ounces of raisins are needed to make 3 lb of trail mix? A. 1.9 oz B. 8.7 oz C. 17.1 oz D. 22.5 oz

It will take 3 time as many ounces of raisins.

3 x 5.7 = 17.1 oz of raisins - answer is C.

A is wrong because it would take more than 5.7 oz for 3 lbs, not less.

B is wrong because even 2lbs would take over 10 oz (using estimation 5 x 2)
