Math question for truck rental prices

Question

1. Research an advertised truck rental price plan that does not include unlimited miles and provide the details of the advertisement. (e.g., $50/day with 200 miles included and $0.10 per additional mile.)
2. Create your own similar truck rental price plan with different values. Be sure to not use the exact same values used in a previous post.
3. Based on your plan, write an equation that can be used to determine the daily cost, D(t) of the rental when t miles are needed, and use that equation to calculate the total cost when 300, 1,000, and 2,000 miles are used.
