Answer 1

2,400 Yens

Step-by-step 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
