Algebra Difficulty 1.1 Junior Find the answer Canada

In a survey, each student chose their favourite day of the week.
In the graph, the percentages of those surveyed who selected each day of
the week is shown.

If $3000$ students were surveyed,
how many people chose Friday as their favourite day of the week?

Pick one

Solution

Reading from the graph, $20\%$
of the students surveyed chose Friday.

Since $3000$ students were surveyed,
the number of students who chose Friday as their favourite day of the
week was $\dfrac{20}{100}\times3000=20\times30=600$ .
