Chapter 6.1, Problem 59PFA

To determine

Find the number of points that each person score.

Answer to Problem 59PFA

The number of points the both the person score are $2$ and $16$ .

Explanation of Solution

Given:

It is given in the question that in a computer game, fermin score was $12$ points less than twice Lisa score. The total of both scores was $18$ .

Now, from the above statement, it has to make a equation from understanding the correct variable.

Let the number of points Lisa has = x .

Then, the number of points Fermin’s has = $2x+12$ ( $12$ points less than twice)

Now, the total points scores = $18$ .

According to question,

  $\begin{array}{l}x+2x+12=18\\ 3x=18-12\\ 3x=6\\ x=2\end{array}$

Now, put the value of x in the above two variable,

The number of points Lisa has = $2$ .

The number of points Fermin’s has =

  $\begin{array}{l}2x+12\\ =2(2)+12\\ =4+12\\ =16\end{array}$
