====================================================
Work Shown:
2% = 2/100 = 0.02
2% of $19,866 = 0.02*19866 = 397.32
Dora earned $397.32 in commission on top of the base monthly salary of $2,212
Her total monthly pay is 2212+397.32 = 2,609.32 dollars

If you wanted to use a bit of algebra here, then the equation is
y = 0.02x+2212
Plug in x = 19866 and you should get y = 2609.32
