Chapter 7, Problem 18CT

To determine

Find the number of people walked in walkathon last year.

Answer to Problem 18CT

Number of people walked in walkathon last year was $1200$

Explanation of Solution

Given information:

Number of people walked last year = $1344$

Percent of people increased this year = $12\%$

Let the number of people walked last year be $x$

:

Now total percent of people this year is = $100\%+12\%=112\%=\frac{112}{100}=1.12$

Now $1344$ is equivalent to $1.12x$ therefore,

  $\begin{array}{l}1.12x=1344\\ \\ x=\frac{1344}{1.12}\\ \\ \boxed{x=1200}\end{array}$

Number of people walked in walkathon last year was $1200$
