Tim decides to get animals for his zoo. He buys 3 goats for $400 each. He gets twice as many llamas which cost 50% more each. How much did he spend?
Stream of thoughts:
4800
The goats cost 3 * 400 = $1200.

He buys 3 * 2 = 6 llamas.

Each llama cost 400 * 1.

5 = $600.

So he spends 600 * 6 = $3600 on llamas.

So the total cost was 1200 + 3600 = $4800.

.

Therefore, the answer is 4800
