Mary has $311.75 to convert into yen. The currency exchange she is using charges a surcharge of 6% when converting currency. About how many more yen will Mary receive if she makes her trade on the day with the most favorable exchange rate than if she makes her trade on the day with the least favorable exchange rate?
Solution:
Of all the days of the week, the most favorable exchange rate day is Friday where the exchange rate is ¥92.7120 and the lease favorable exchange rate day is on Wednesday where the exchange rate is ¥87.5507.
If Mary converted the currency, she will receive only 94% of her money excluding 6% surcharge.
Favorable day(Friday)= ($311.75) x (92.7120/1) x 0.94
=¥27,168.788
Least Favorable day(Wednesday) =($311.75) x (87.5507) x 0.94
=¥25,656.294
The difference between most favorable day and least favourable day = ¥27,168.788 - ¥25,656.294
= ¥1,512.49
