answer attempt 1 out of 2
cost of parking for 3 hours:
cost of parking for t hours:

Explanation:

Step1: Define cost structure

Fixed fee: $\$9$, hourly rate: $\$2$

Step2: Calculate 3-hour cost

Total cost = Fixed fee + (Hours × Hourly rate)
$\text{Cost} = 9 + (3 \times 2)$
$\text{Cost} = 9 + 6 = 15$

Step3: Write t-hour cost formula

Total cost = Fixed fee + (Hours × Hourly rate)
$\text{Cost} = 9 + 2t$

Answer:

Cost of parking for 3 hours: $\$15$
Cost of parking for t hours: $\$9 + 2t$
