Answer:
$13.52
Step-by-step explanation:
- So, the exchange rate between American and Singapore dollars is significant.
- Seeing that American dollars are "cheaper" than Singapore dollars, & that we're converting to Singapore dollars "which cost more in value." We'll multiply.
- Now, 1 American dollar is 1.3 Singapore dollars, & the book is costing 10.40 American dollars.
- We'll multiply 1.3 (Singapore dollars) with 10.40 (American dollars)
- Our answer is 13.52 Singapore dollars.
That's the answer, hope it helps!
