Chapter 1.6, Problem 2P

To determine

To calculate:Money Jo and Lyn have

Answer to Problem 2P

Jo has $21 and Lyn has $42.

Explanation of Solution

Given information:

They both have $63 and Lyn have 2 times more money than Jo.

Calculation:

Let us assume Jo has $x and Lyn has $2x

So, according to question,

  $\begin{array}{l}x+2x=63\\ \Rightarrow 3x=63\\ \Rightarrow x=\frac{63}{3}\\ \Rightarrow x=21\end{array}$

Since, x=21

Therefore, Jo has $21 and

Lyn has $\$2x$

So, putting the value of x in the above equation we get-

  $2\times 21=42$

Therefore, Lyn has $42.

So, Jo has $21 and Lyn has $42.
