Today hugo got a new credit card, and he made a purchase of s$1400. the card offers an introductory apr of 0% for the first 5 months and a standard apr of 30.8% thereafter. if the card compounds interest monthly, how much money will the introductory apr save hugo in interest over the first 5 months? (assume that hugo will make no payments or additional purchases during the first 5 months, and ignore any possible late payment fees.)
