Final answer:
The initial question about the cost of wrapping paper lacks enough data to provide an answer. Instead, examples are given of how to handle budgeting and probability problems using high school level mathematics.
Step-by-step explanation:
The question asked about Kim and Mike selling wrapping paper and finding the cost of one roll each of plain and holiday wrapping paper appears to be missing the necessary information to solve the problem. In mathematics problems, such as those often found in algebra or arithmetic, specific numerical data is required to find a solution. Without such information, it is not feasible to determine the cost of the wrapping paper.
However, there are other parts of the supplied text related to different mathematics problems.
For instance, if we consider Marie's weekly budget for magazines and pies, we could develop a mathematics problem where we calculate the combination of magazines and pies she could purchase within her $24 budget.
Similarly, if we explore the envelope picking scenario with the free gift coupons, we could calculate the expected value or the probability of picking an envelope with a certain gift value.
Without the pertinent details for Kim and Mike's school fundraiser, these other problems could serve as examples of typical high school level mathematics questions involving budgeting and probability.
