To determine

Tocalculate: to calculate the no. of points to be required to got to next level

Answer to Problem 23P

The 15 points are required to go to next level

Explanation of Solution

Given: current points =40

Loss of points = 5

Calculation:

Let the points needed to go to next level be $x$

Current points = 40

Loss of points = 5

Total points $=40-5+x$

  $=35+x$

  $\begin{array}{l}35+x\ge 50\\ x\ge 50-35\\ x\ge 15\end{array}$

More than 15 points are required to go to next level.
