Translate the problem situation to a system of equations. Do not solve.Audreys Candy Store sold 64 individual pounds of jelly beans, one kind at $4.74 per pound and the other at $1.23 per pound. In all, $162.96 was taken in for the two types of jelly beans. How many pounds were sold?
A. x + y = 162.96; 4.74x + 1.23y = $64 B. x + y = 64; 4.74x + 1.23y = $162.96 C. x + y = 5.97; 4.74x + 1.23y = $162.96 D. x + y = 64; 5.97x + y = $162.96
