Chapter 13.3, Problem 50E

Work these exercises (See Example 6.)

Specialty Foods In specialty food stores, the rate of sales (in billions of dollars per year) can is approximately

$f\left(x\right)=2.25\ln \left(x\right)+14\left(x\ge 1\right),$

where $x=1$ corresponds to the year 2001. Find the function $F\left(x\right)$ that gives total sales between the year 2001 and year x. (Data from: Annual Retail Trade Survey.)
