Question

Sophia got 68 pointa correct on her math test, which earned her an 85% her friend Tami scored 71 points on the same test. How many total points were on the test?

Answer 1

We can solve this problem by applying the rule of three:

`\begin{gathered} 85\text{ \% ----- 68 points} \\ 100\text{ \% ---- x} \end{gathered}`

then, x is equal to

`x=((100)(68))/(85)`

which gives

`\begin{gathered} x=(6800)/(85) \\ x=80 \end{gathered}`

that is, the test consists in 80 points.
