135. Story Problems, and a new wrinkle

Some story problems I made yesterday for tomorrow’s Year VII math class:

1. A book club sells memberships for $20 a year. A lifetime membership is $150. How long does it take to get your money’s worth?
[This was inspired by the LiveJournal situation.]

2. Suppose you want to rent a car for a three-week trip. The daily rate is ¥6,000. The monthly rate is ¥100,000. Should you rent by the day or by the month?

3. The Kitajima MaxValu sells six 350ml cans of ^root beer for ¥680. The same ^root beer is available in six 500ml cans for ¥990. Which is the better buy? (Tip: Always bring a calculator shopping, or use the calculator on your keitai.)

4. Next to the MaxValu, the Skylark sells a personal-size 320g pizza for ¥450. There’s also a large 960g pizza for ¥1575, but it requires two people to eat. Should you bring a friend to Skylark?

5. The JR train costs ¥20 per kilometer, plus a ¥120 fee. A competing bus service charges ¥18 per kilometer. You will be going to Kirimatsuwakashiimamiyayama, which is 115km away by train, but 145km by bus. Which way should you go?

6. What would you do if you knew that the train moved at 45 km/h and the bus at 75 km/h?

Uh-oh – it looks like we’re getting audited!

Hello, English teachers from SMU

The representative from SMU, Ms.M.A., will visit us in November.
She will observe your lessons and have individual meeting with you.

I will let you know when the details of her visitation is decided.


It’s put up or shut up time!
