Question

You need to exchange some of your U.S. Dollars for Australian dollars. For every U.S. Dollar, suppose you get $1.468 in Australian dollarys. If you already have $32.45 in Australian dollars, how much in U.S. Dollars do you need to exchange to have $766.45 in Australian dollars?

Answer 1

Answer: $500

Explanation:

You already have $32.45 in Australian dollars. You however want to have a total of $766.45. You therefore need an extra:

= 766.45 - 32.45

= A$734

1 USD gives A$1.468

The USD you will need is:

= 734/1.468

= $500
