13) What answer contains the correct equations for this context?*
The student council at Jefferson High School
sold a total of 220 brownies and cookies during
its fund-raiser. Each brownie sold for $0.75,
and each cookie sold for $0.50. The student
council made $136.50 from the sales of
brownies and cookies. Which system of linear
equations can be used to find b, the number
of brownies sold, and c, the number of cookies
sold?
A. b + c = 220
0.506 + 0.75c = 136.50
B. b + c = 136.50
0.75b + 0.50c = 220
C. b + c = 136.50
0.50b + 0.75c = 220
D. b + c = 220
0.75b + 0.50c = 136.50
