Answer:
$180.806
Explanation:
The computation of the total amount paid for the trip is shown below;
As we know that
Simple interest = Principal × rate of interest × time period
= (67.70 + 62.34 + 45.50) × 12% × 3 months ÷ 12 months
= 5.2662
Now the amount is
= Principal + simple interest
= 175.54 + 5.2662
= $180.806
