Question 1172270
<font color=black size=3>
The chart says "protein: 21 g"
This applies to one energy bar. So we could say
1 bar = 21 grams of protein
n bars = 21n grams of protein
Simply multiply both sides by n
n is a placeholder for a positive whole number


For instance, if n = 3, then
n bars = 21n grams of protein
3 bars = 21*3 grams of protein
3 bars = 63 grams of protein


Therefore, the equation is
p = 21n


There's no need to solve for p because p is already isolated on its own side, and there's nothing else on the left side.


If you wanted to solve for n, you would divide both sides by 21 to get p/21 = n, which is the same as n = p/21.
