How I learned is to do a formula. So what I do is a=PW
Is=p(of)
A=0.158(200)
__________
158. 158
answer=20 (after you divide 31.6 by 158 times it by 100 then that's your answer)
The greatest amount of money would be $105.40. The least amount would also be $105.40. Because the zero is less than five the dollar amount would stay the same.
