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.

You can put this solution on YOUR website!
No, the units of h,f, and p are grams while 4,9,4 are in calories/gram.
You have everything you need.
+C=4h%2B9f%2B4p
+h=31
+f=0
+C=130
+130=4%2831%29%2B9%280%29%2B4p
Solve for p.
+130=124%2B4p
+6=4p
+p=1.5+
1.5 grams of protein are in 130 calories worth of raisins.
