Let’s check out your problem:

Each cup of cooked brown rice has $216$ calories and $5$ grams of protein. Each cup of kidney beans has $220$ calories and $16$ grams of protein. Which of the following systems of equations could be used to determine the amount of rice, $r$, in cups, and the amount of beans, $b$, in cups, that should be eaten in order to consume $435$ calories and $18$.$25$ grams of protein?$\newline$Choose $1$ answer:$\newline$(A) $216 r+5 b=435$$\newline$$220 r+16 b=18.25$$\newline$(B) $216 b+5 r=435$$\newline$$220 b+16 r=18.25$$\newline$(C) $216 r+220 b=435$$\newline$$5 r+16 b=18.25$$\newline$(D) $216 b+220 r=435$$\newline$$5 b+16 r=18.25$
