If 7 ounces of cola costs $0.59. How much should 15 pounds cost ?

3 answers

Convert 15 pounds to ounces: 15*16=240

Make a proportion: 0.59/7=x/240

You do the rest. Hope this helps.
7 oz * 1 lb/16 oz = 7/16 lb

so 15 lb * $0.59/ (7/16) lb = 15 *16/7 * $0.59 = $ 20.23
LOL, either way, in pounds or in ounces
