A store is designing the space for rows of nested shopping carts. Each row has a starting cart that is 4 feet long, followed by the nested carts (so 0 nested carts means there's just the starting
cart). The store measured a row of 13 nested carts to be 23.5 feet long, and a row of 18 nested
carts to be 31 feet long
1. Create a graph of the situation.
2. How much does each nested cart add to the length of the row? Explain your reasoning
3. If the store design allows for 43 feet for each row, how many total carts fit in a row?
