The adoption fee for an untrained dog is $150.
The cost for 12 weeks of training is $250 per week, so 12 weeks x $250/week = $3000.
The certification costs are $3000, but 90% of it is covered by insurance, so John needs to pay 10% of $3000 which is $3000 x 10% = $300.
The total cost for John is $150 + $3000 + $300 = $3450.
Therefore, the out-of-pocket cost for John is $3450.
#### 3450
