Short Answer

Expert verified

The equation that is used to find on average how much the annual per-pupil spending

has increased from 1986 to 2001 is $x = \frac{(\begin{array}{l} annualperpupil \\ spending2001 \end{array}) 鈭� (\begin{array}{l} annualperpupil \\ spending1986 \end{array})}{2}$

Step by step solution

– Describe a variable.

To solve the word problems, it is necessary to define a variable and form an equation.

For this problem, choose a variable that gives the average annual per-pupil spending has increased from 1986 to 2001.

– Write an equation that describes the given situation.

From the graph, the annual per-pupil spending in 1986 is $3, 479$ and the annual per-pupil spending in 2001 is $7, 489 .$

Write the equation as follows:

$\begin{matrix} averageannualfrom1986to2001 = \frac{(\begin{array}{l} annualperpupil \\ spending2001 \end{array}) 鈭� (\begin{array}{l} annualperpupil \\ spending1986 \end{array})}{2} \\ x = \frac{(\begin{array}{l} annualperpupil \\ spending2001 \end{array}) 鈭� (\begin{array}{l} annualperpupil \\ spending1986 \end{array})}{2} \end{matrix}$
