Sorry I meant to add that the British government may not agree with my
analysis. Recently the rate of national insurance (a tax) was increased from
10% to 11% which the government helpfully explained (wrongly) was a 1% and
not a 10%increase but that's just taxes!!

Here's a scenario:

Week 1
Visits to store = 100
Purchases = 1
Purchase rate = 1%

Week 2
Visits to store = 200
Purchases = 4
Purchase rate = 2%

Here's the question:
What is the increase in my purchase rate?

Is it 1%? Is it 100%?

Thanks for your help!
