Answer:
2,400 Yens
Explanation:
exchange rate for buying Japanese Yen is 12 Yens per Dollar
1 dollar : 12 Yens
how many Yens do you need to buy 200 Dollars for?
Let
x = number of Yens needed
200 dollars : x Yens
Equate the ratios to find x
1 dollar : 12 Yens = 200 dollars : x Yens
1/12 = 200/x
Cross product
1 * x = 12 * 200
x = 2,400
x = number of Yens needed = 2,400 Yens
