Translate the problem situation to a system of equations. Do not attempt to solve.Sarah Comar's Candy Store sold a total of 33 pounds of jelly beans, selling two kinds of jelly beans. The first kind was priced at $3.45 per pound, and the second was priced at $1.12 per pound. In all, $83.56 was taken in for the two types of jelly beans. How many pounds of each kind were sold? (Let x represent the number of pounds of the first kind and y represent the number of pounds of the second.)
A. x + y = 33, 3.45x + 1.12y = 83.56 B. x + y = 4.57, 3.45x + 1.12y = 83.56 C. x + y = 33, 4.57x + y = 83.56 D. x + y = 83.56, 3.45x + 1.12y = 33
