Person a has a large van that gets 15 miles per gallon and person b a small car that gets 30 miles per gallon. A drives 150 miles and B 50 miles per week. They decide that they can afford to buy both. What vehicle would the save the most money

If person a has 15 miles per gallon and drive 150 miles a week they would have to full there van 10 times a week. Person b has 30 miles per gallon and drive 50 miles a week would have to fill up there car 2 times a week. So person b with there small car would save the most money
