Question

In 1995, 480 high school seniors at Boyertown had pagers (not cell phones!). Every year that number decreased by 19%. Write an equation to represent the number of seniors that have pagers. According to your equation, how many seniors had pagers in 2003?

Answer 1

n 1995, 480 high school seniors at Boyertown had pagers

Number if students have pagers = 480

Every year that number decreased by 19%.

Amount of students decrease 19% of 480

`\begin{gathered} \text{ 19\% of 480=}(19*480)/(100) \\ \text{ 19\% of 480=91.2} \\ \text{ 19\% of 480}\approx19 \end{gathered}`

Amount of studnets decareases every year : 19

Let x be the number of years and y be the number students have pagers :

y= 480-19x
