Question 183970
<font face="Times New Roman" size="+2">


Let <i>x</i> be the decimal fraction increase, then:


*[tex \LARGE \text{          }\math 12000(1 + x) = 14000\ \ \Rightarrow\ \ 12000 + 12000x = 14000\ \ \Rightarrow\ \ 12000x = 2000\ \ \Rightarrow\ \ x = \frac{2000}{12000} = \frac{1}{6} \approx 0.167]


Change *[tex \Large 0.167] to a percentage by moving the decimal point two places to the left, 16.7%
