Translate the problem situation to a system of equations. Do not solve.Sarah Comar's Candy Store sold 38 individual pounds of jelly beans, one kind at $3.57 per pound and the other at $0.91 per pound. In all, $58.52 was taken in for the two types of jelly beans. How many pounds of each kind were sold?
A. x + y = 58.52; 3.57x + 0.91y = $38 B. x + y = 38; 4.48x + y = $58.52 C. x + y = 38; 3.57x + 0.91y = $58.52 D. x + y = 4.48; 3.57x + 0.91y = $58.52
