Pizza Mogul

In Australia, Dominos Pizza have a site that let's you design and sell your own pizza. Interestingly you earn between $0.25 and $3.25 each time someone orders your pizza.

I stumbled across this article in the news

Interestingly the highest earners are on track to earn $100 000 this year. Pizza maker could make $100000

I showed it to my lovely math class and they are inspired to try and raise enough cash for an "awesome -end-of-the-school-year-pizza-Christmas-party." As a first step they have come up with a budget for the things they want at their party-a goal they have to try and raise. They then have to calculate earning targets...based upon their budget they have to earn about $2500 in 13 weeks, but they have not considered the wants vs needs for the party.

One of my students astutely pointed out that they are not going to make any money if they do not have a decent pizza flavour or advertising strategy. So as a next step, half the class are researching and surveying preferred flavours. The other half will be trying to find the most effective advertising strategy. Maybe they will raise the cash, maybe they won't, but it is fascinating to see them work so cohesively as a team and engaging in mathematics. 

In the interim, The pizza mogul app has a leader board has information regarding the top sellers, the amount made and the number of pizzas sold. The timer rests every 28 days. At what rate are the leaders earning their money?

UPDATE: I heard back from Dominos who confirmed that each topping on the pizza earns the creator $0.25 up to a maximum of $3.25...I have an idea in mind to use this information in my graphing unit over the next few weeks, once I get that off the ground I will share.

Who does more housework, males or females is always a contentious issue. However a recent study in Japan has suggested that married women do 80% of the housework.

Women do more housework.

The results of the survey suggest that over 40% of women are unhappy with their husbands involvement in household chores. The results were collected through a simple survey method.

However, the survey only involved 6409 women. What percentage of Japan's women is that?

What could be the flaw in the data?

Something that could support this article is an OECD report that Japan's men spend the least amount of time on housework (see image below)

Lower taxes-more jobs

Apparently lower taxes can lead to more jobs. This article is a really interesting study in the effect of lower taxes on job creation.

Lower taxes can lead to more jobs

The reporter admitted to making a mistake in analysing the data. What was it?

All relevant data can be found here: BLS Household Survey

I find it interesting that the low tax states have experienced fasted economic growth. What reason could there be for that?

Based upon the job growth figures per state, one could construct a graph that compares job growth per state. What would that demonstrate?
