Explanation:

Step1: Identify initial cost

When time $t=0$, cost $C=1$, so unlock fee is $\$1$.

Step2: Calculate per-minute rate

Use point $(10,4)$. Rate = $\frac{4-1}{10-0} = \frac{3}{10} = 0.30$.

Step3: Match to options

Cost function: $C = 1 + 0.30t$, which matches the third option.

Answer:

The graph represents a function showing the total cost of renting the scooter over time.
There is a $1 fee to unlock the scooter, and then it costs $0.30 per minute after that.
