Answer:
$22.80
Step-by-step explanation:
Given:
1 day trip costs = $6.30
Monthly working days = 16
Monthly pass = $78
Let's calculate the metro train costs for 16 days.
We need to multiply $6.30 by the number of days.
= 6.30 * 16
= $100.80
You suppose to pay $100.80 if you are not taking the pass.
If you take the monthly pass, you just need to pay $78.
The amount saved if you took the monthly pass = $100.80 - $78 = $22.80
