Cupcakes and Brownies Sales Problem

Very Hard Word Problems Algebraic Reasoning

During a school fair, James and Mia are managing separate booths. James sells cupcakes for $3 each, and Mia sells brownies for $4 each. After selling a total of 37 items, they earned $111 together. If the number of cupcakes James sold is represented by c and the number of brownies Mia sold is represented by b, which of the following equations can be used to determine how many of each item they sold?

Consider the total number of items sold and the total revenue generated.

$c + b = 37$ and $3c + 4b = 111$

$c + b = 37$ and $4c + 3b = 111$

$c + b = 111$ and $3c + 4b = 37$

$3c + 4b = 37$ and $c + b = 111$
