Question

Mario made a 75 on his last test. If he scores 20% higher on this test, what will be his higher test score?

Answer 1

We can answer this by the rule of three.

`\begin{gathered} 75\rightarrow100 \\ x\rightarrow120 \end{gathered}`

Then:

`x=(120\cdot75)/(100)=(9000)/(100)=90`

Therefore his score will be 90 points.
