John bought 18 erasers.
Explanation: He has $6.00
He spends $3.12 on notebooks
Then you do $6.00 - $3.12 and you get $2.88
If it’s ¢16 per eraser and he has no money left over after buying erasers than you would divide $2.88 by $0.16 which turns into 288 divided by 16 which comes out to 18.
Therefor John bought 18 erasers.
