Monday Math Challenge
Entry Point One
I’m thinking of a number. Let’s call it n.
- 2n + 2 = 40
- n - 9 = 10
What does n equal?
Entry Point Two
Mr. Adams wants to show Room 1 how good vegetarian pizza can be. He orders enough pizzas for everyone in Room 1 to have two slices.
- There are 21 students in Room 1, but two are absent.
- Mr. Adams eats three slices, but Miss Park is only hungry enough for one.
- Each pizza is cut into 8 slices.
How many pizzas does Mr. Adams need to order? Are there any slices left over? If so, how many?
Entry Point Three
Luke saves and Acea spends.
Acea finds a $20 note on Sunday evening and spends $2 a day starting on Monday.
Coincidentally, Luke starts work on Monday and gets $2.50 a day.
How long will it be before Acea has more money than Luke?

Entry Point Four
I’m thinking of another number. We’ll call this one x.
- 3x - 1 = 2x + 6
What does x equal?
Entry Point Five
Laura can paint a room by herself in 3 hours. Saskia can do it in 4 hours.
Ellie would take 6 hours on her own. If they all work together and don’t get in each other’s way, how long will the job take?
