Output error

DEnumber50 (147)
I am trying to get the output income to be only to 2 decimal places, I attempted the cin.precision(2) but the number outputted is something way off. Let me know what I need to change to make it display correctly. I don't know what I am missing.

cout << fixed << setprecision(2);
