Question: Explain how to solve this math problem: Theo has $6000 he wishes to spend on his upcoming business trip to South Africa. He buys 6 business suits at $100 each, 3 suitcases at $50 each, a flight ticket that costs $700 more than 5 times as much as the cost of a business suit. He wishes to save $2000 for this trip, how much does he have to spend on buying gifts for his business partners in South Africa?
Answer: 
Theo buys business suits for 6 suits * $100/suit = $600.
Theo buys suitcases for 3 suitcases * $50/suitcase = $150.
Theo buys a flight ticket that costs $700 + 5 * $100 = $1200.
Theo can spend $6000 - $600 - $150 - $1200 - $2000 = $2050 on gifts for his friends.
