Jonathan and his friend from Japan, Hiro, are at a stationery shop in London. Jonathan wants to buy a set of pens costing 15 pounds. Hiro has 20 US dollars. The shop accepts both pounds and US dollars with a conversion rate where 1 pound equals 1.35 USD. Additionally, Jonathan has already spent 3 pounds on another item using the store's gift card, which can also be applied to the set of pens.
