John buys 1.5 ounces of silver and twice as much gold. The silver costs $20 per ounce. The gold is 50 times more expensive per ounce. How much does he spend on everything?
Let's think step by step.
3030
He buys the silver for 1.

5 * $20 = $30.

He bought 1.

5 * 2 = 3 ounces of gold.

The gold is worth %20 * 50 = $1000 per ounce.

So he buys 3 * $1000 = $3000 on gold.

So he spent $30 + $3000 = $3030 on everything.

.

The final answer: 3030
