Super Challenge/Kua takoto te Manuka

Question - Thursday

Each day, Monday to Thursday there will be one tricky question for you to answer.  The answer will be a number.

Students will need to record their daily answers.

On Friday, students can submit their Super Challenge daily answers, and the total of the daily answers, and submit them online.

If this total is correct, they will get a link to a page where they can fill in their name and school. Students can then print out their Maths Week Super Challenge

Certificate. The student’s school will also get a notification of their success.

If the total is incorrect, a message comes up to tell the student. The student can then go back, change an answer, and re-submit it. If the total is then correct, the student will get the Maths Week Super Challenge Certificate.

The answers to the Super Challenge questions will be available to teachers after the end of Maths Week.

I mix two blends of tea leaves, A and B, to sell. A costs $30 per kilogram and B costs $60 per kilogram. I mix $120 worth of A and $120 worth of B.

What should be the minimum number of dollars per kilogram I should charge for the blend to cover the cost of the ingredients?

(The answer is not $45.) Note – do not include the $ when you submit your answer.
