<human>:  An 8-year old child wants to buy a toy car which costs $12. He already has $4 savings. How many days will it take him to save the remaining amount of money if he promises to save $2 daily from his allowance?
<bot>: How much money does the boy still need? ** The boy still needs $12 - $4 = $<<12-4=8>>8.
How many days will it take him to save the remaining amount? ** If he saves $2 per day then it will take him $8 / $2/day = <<8/2=4>>4 days to save the remaining amount.
