完整解法

1. Determine the charge for the first hour

Since Tuesday falls under 'Monday to Thursday', the charge for the 1st hour is $\char36{}2.70$ .

2. Calculate the remaining time after the first hour

Total parking time = $3$ hours.
Remaining time = $3 - 1 = 2$ hours.

3. Determine the number of subsequent 30-minute blocks

$2$ hours = $2 \times 60 = 120$ minutes.
Number of 30-minute blocks = $120 \div 30 = 4$ blocks.

4. Calculate the total charge

Charge for subsequent blocks = $4 \times \char36{}1.30 = \char36{}5.20$ .
Total charge = $\char36{}2.70 + \char36{}5.20 = \char36{}7.90$ .

答案

$7.90
