(0.12 + 0.1 + 0.2222)450 = 198.9

400 - 199 = $201
I don't think so since the answer is nothing to the choices
A. $144
B. $199
C. $251
D. $277
My answer was only $2.00 off. That can be accounted for by the fact that I used a decimal for the fraction. Using the fraction -- here's the answer.

(0.12 + 0.1)450 = 99

(2/9) * 450 = 900/9 = 100

100 + 99 = 199
