I just did the mock exam, as question I faced was to work out the APR of 1.5% per month for a credit card company. The answer is;
(1+0.015) 12- 1 = 0.1956 =19.56%.
On my calculator I cannot seem to get this answer when I try. Is there a specific order that I need to work this out in? (The 12-1 part I do using the squared button which I fill in with 12-1)
