Emma has been saving up to go on a big summer trip, visiting the United States and Russia. After working hard throughout the year, she has a total of £2500 in spending money.
The exchange rates are:
£ 1 = $ 1.28, and
$129.35 Rubles
Emma has also discovered that the maximum amount of money she can enter Russia with is 32 285 Rubles.
Assuming Emma wants as much cash as possible in Russia, how much should she spend while in the United States?
