Answer:
416.67 dollars
Step-by-step explanation:
the exchange rate between U.S. dollar and euro is given as
Exchange rate = 1:0.6
1 U.S. dollar /1 euro = 0.6
cross-multiplying both side
1 x 1 U.S. dollar = 0.6 x 1 euro
1 U.S. dollar = 0.6 euro
multiplying both side by 10
10 U.S. dollar = 0.6 x 10 euro
10 U.S. dollar = 6 euro
dividing both side by "6"
10 U.S. dollar/6 = 6 euro/6
(10/6) U.S. dollar = 1 euro
1 euro = (10/6) U.S. dollar
the ring was bought for 250 euros , we need to convert 250 euros in dollars.
multiplying both side by 250
250 x 1 euro = (250 x 10/6) U.S. dollar
250 euro = 416.67 U.S. dollar
so liza should pay 416.67 U.S. dollar to marie.
