<human>:  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?
<bot>: How much does the silver cost? ** He buys the silver for 1.5*$20=$<<1.5*20=30>>30
How much does the gold cost? ** He bought 1.5*2=<<1.5*2=3>>3 ounces of gold
How much is the gold worth? ** The gold is worth %20*50=$<<20*50=1000>>1000 per ounce
How much does he spend on gold? ** So he buys 3*$1000=$<<3*1000=3000>>3000 on gold
How much does he spend on everything? ** So he spent $30+$3000=$<<30+3000=3030>>3030 on everything
