Natasha went to Japan for a business trip. Natasha converted $1100US into 110682 Yen at the local bank. Natasha spent 87438.78 Yen on this trip and returned with the remaining Yen to the US.

Question

How much will the remaining Yen convert to in US Dollars when Natasha returns from Japan? Assume the conversion rate stays the same.

Answer 1

Number of Yen remaining = 110682 - 87438.78
= 23243.22

$1100US = 110682 Yen
1 Yen = 1100/110682 = $.009938382
so 23243.22 Yen = .009938382(23243.22)
= $231

or
1100/110682 = x/23243.22
x = 231
