The metro train costs $6.30 round trip to ride to work each day. you work 4 days a week (16 days a month). if you can get a monthly pass for $78, how much money can you save by buying the pass?

$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

saving = more money

step-by-step explanation:

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.
