<human>:  James decides to pick some blueberries. It cost $20 to go picking and then another $1.5 per pound. He picked 30 pounds of blueberries. How much did he save compared to buying at the store for $2.5 a pound?
<bot>: How much did he pay for the blueberries he picked? ** He paid 30*1.5=$<<30*1.5=45>>45 for the blueberries he picked
How much did James pay in total? ** So after the entrance fee it was 45+20=$<<45+20=65>>65
How much would it cost to buy them at the store? ** To buy them at the grocery store it would cost 30*2.5=$<<30*2.5=75>>75
How much did James save? ** So he saved 75-65=$<<75-65=10>>10
