Question 1181455
<br>
Calculate the percent increase or decrease in a measurement equivalent to two or more successive increases or decreases by viewing each increase or decrease as a multiplication by some factor instead of an addition or subtraction.<br>
An increase of 40% (from 100% to 140%) means multiplication by a factor of 1.40 = 1.4; an increase of 10% means multiplication by a factor of 1.10 = 1.1.<br>
Then an increase of 40% followed by an increase of 10% means multiplication by successive factors of 1.4 and 1.1.<br>
{{{(x)(1.4)(1.1) = 1.54x}}}<br>
ANSWER: The percent increase from 1950 to 2012 is 54%.<br>
