Question

o Marcella bought a 25-ounce bottle of olive oil for $5.88. She used 60% of the olive oil in two weeks. Which of the following is closest to the cost of the oil she used? F $0.24 G $0.39 H $2.35 J $3.53

Answer 1

First divide the price of the olive oil by the volume of the olive oil to find the price per ounce.  5.88/25oz=0.2352 dollars/ounce.  Then you have to multiply the volume of the bottle by .60 to find what 60% of the volume is. 0.60x25=15 ounces.  since in the first two weeks she used 15 ounces which has a price of 0.2352 dollars/ounce you have to multiply 15 by 0.2352 which equals 3.528 dollars.
