a parking lot charges 1.50 for the first hour of parking and 55 cents for each additional half hour. How much would it cost to park a car from 12:45 pm to 6:15 pm

That's 5.5 hours or 11 half-hours

1.50 + (0.55 * 9) = ?

0.55 { 9}= 4.95 + 1.50 = 6.45

a parking lot charges 1.50 for the first hour of parking and 55 cents for each additional half hour. How much would it cost to park a car from 12:45 pm to 6:15 pm

To calculate the cost of parking a car from 12:45 pm to 6:15 pm, we need to determine the total duration of the parking and then calculate the corresponding charges.

Step 1: Calculate the duration of parking
The car was parked from 12:45 pm to 6:15 pm, which is a total of 5 hours and 30 minutes.

Step 2: Determine the charges
The parking lot charges $1.50 for the first hour, which we will consider for the first 60 minutes of parking. Any additional time is charged at a rate of 55 cents for each additional half hour (or 30 minutes).

For the given duration of 5 hours and 30 minutes:
- The first hour is charged at $1.50.
- The remaining 4 hours and 30 minutes can be divided into 4 half-hour intervals.
- Each half-hour interval will incur a charge of 55 cents.

Step 3: Calculate the total cost
- First Hour: $1.50
- Half-hour intervals: 4 x $0.55 = $2.20

Adding up the charges:
$1.50 (first hour) + $2.20 (half-hour intervals) = $3.70

Therefore, the total cost to park a car from 12:45 pm to 6:15 pm would be $3.70.
