Where the options i need your options in order to give you the exact answer.
A) if you have USA 25$ times INR 39.41$ it would be 985.25$ in US money, hopefully.
B) 1. 25 US dollars would be 25 Canadian dollars. 2. US 25$ times EUR 1.69 equals US 42.25. US 25$ times ZAR 6.78 equals US 169.5. so it would be cheaper to buy supplies in south america, because the 25 US dollars you brought from home would turn into 169 dollars and 50 cents. 3. im not sure how to get the third answer, and dont quote me on the questions either.
