The first 3 digits of the number are 2, 3, 3. The next digit is 5, which is more than 4, so 1 is added to the digit to its left and all digits to the right of the first three are dropped.
2.33 becomes 2.34 because of the 5 in the thousandths place.
The formula is A=p (1+r)^t A future value? P current value 140 R rate of inflation 0.034 T time 2008-2005=3 years A=140×(1+0.034)^(3) A=154.77 round your answer to get A=155
