Maths in real life

Last night my grandma gave me a money jar to spend in Bali and didn’t know how much was in it. So I opened it and counted the money. In the jar was $126.20! But that was in Australian dollar and we had to see how much I would get in Indonesian rupiah. So I searched it up and it said that $1 Australian dollar is $10413 Indonesian rupiah. Then I saw that $126.20 Australian dollar is $1312088.40 Indonesian rupiah. The I work out that 5 cents is $520 Indonesian rupiah.
