Josh and Racquel sold cookies and brownies at the math club bake sale. The cookies cost $0.47 each, and the brownies cost $0.60 each. They sold a total of 603 items (cookies and brownies) and raised $323.84 Write a system of equations and determine the number of cookies sold and the number of brownies sold.
Could you please show the work on how to do this?

just put the facts into symbols, one item at a time:
cost of c cookies = .47c
cost of b brownies = .60b
c+b = 603
.47c + .60b = 323.84
now, you know that c = 603b, so
.47(603b) + .60b = 323.84
283.41  .47b + .60b = 323.84
.13b = 40.43
b = 311
c = 603311 = 292
