Answer:

  $143.13

Step-by-step explanation:

Tax and tip are added to the bill to obtain the total paid. The tip here is presumed to be figured on the original bill amount, so we have ...

  total paid = bill + 4.5% × bill + 10% × bill

  = bill × (1 +4.5% +10%)

  = bill × 1.145

  total paid = $125 × 1.145 = $143.13

The family pays $143.13.
