Last question on the last exercise is wrong. 100(0.05/366 +1)^183=102.53

Great slides, but a couple of things I spotted: Slide 4: 40% of 90 is 36 Slide 6: Surely Charlie spent 15% of £800=£120 on food.

Slide 39 Q7 - the solution is incorrect. Fixed Rate has been calculated as simple interest and it states it is compound interest. Conclusion is correct but the comparable figures that would support it are wrong.
