Answer:
62 Indian ruppes
Step-by-step explanation:
We were told in the question that:
The expression 6.4d - 2 gives the number of Indian rupees you receive when you exchange $d at the local currency exchange.
The amount of Indian rupees you receive when you exchange $10 is calculated as:
6.4d - 2
d = $10
Hence:
Amount of Indian rupees = (6.4 × 10) - 2
= 64 - 2
= 62 Indian ruppes
