John goes to the market and buys 3 goats for $500 each and 2 cows for $1500 each. How much money did he spend?
assistant
How much do the goats cost? ** The goats cost 3*500=$<<3*500=1500>>1500
How much do the cows cost? ** The cows cost 2*1500=$<<2*1500=3000>>3000
How much money did John spend? ** So in total he spends 1500+3000=$<<1500+3000=4500>>4500
#### 4500
