Question 310471: It is given that the formula is C=4h+9f+4p: C=calories h=carbohydrates f=fat p=protein
the question is a serving of raisins contain 130 calories and 31 grams of carbohydrates. If the raisins are fat free how much protein is provided by this serving.
I believe I am missing a formula to convert calories into grams. This is what I have so far:
130 cal.=4(31 g.)+ 9(0 g.)+4p
130 cal.= 1244g. +0g.+4(x) g.
130 cal.= 1244g. +4x g.

Question 333608: A store sells storage bins that are 15 1/4 inches in length. Tom wants to line his wall with these bins. If his wall is 5 yards long, how many of these bins will fit along the wall? I tried 5 divided by 15 1/4, but the answer resulted did not seem correct.
