Final answer:
Without the constant weekly saving amount, we cannot create a specific linear equation for Kara's savings. However, a general form of the equation given a constant amount saved each week would be d = k * w, with d representing total dollars saved, k the constant weekly saving amount, and w the number of weeks.
Step-by-step explanation:
The question asks us to find out how much money Kara can save over a certain number of weeks. We are to assume that the amount saved each week is constant and allows us to create a linear relationship between the total amount saved and the number of weeks. This type of problem is often referred to as a linear function in algebra.
To solve part A, we need an equation d = k * w, where d represents the total dollars saved, k is the constant amount saved each week, and w is the number of weeks. However, the information provided in the question doesn't give us the actual amount saved per week by Kara, therefore we cannot determine the specific value of k for Kara's situation without additional information.
For part B, assuming we had the value of k, we would simply substitute 24 for w in the equation to find out how much is saved over 24 weeks: d = k * 24.
