Question 198069
<font face="Garamond" size="+2">


Let <b><i>x</i></b> represent the number, then:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 1.2x = 45 \ \ \Rightarrow\ \ x = \frac{45}{1.2}]


So 80% of the number is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ .8\left(\frac{45}{1.2}\right)]


You do the arithmetic.
