I think I would add up all the costs, then subtract that from 10,000.

how about bus fare,is it multiply by 1 or 2

Ms. Sue yesterday at 12:10pm
Multiply the bus fare by 2.

Why should i multiply by 2 while the question state it is per journey please any more clarification.

We assume she took the bus both to the market and back home again -- two trips.
