Final answer:
The original question regarding Kelli's pajama purchase cannot be answered without the graph. For Marie's budget questions, she can buy a maximum of 6 magazines or 2 pies with her $24 budget. Jade's opportunity cost for purchasing a pie is 3 magazines.
Step-by-step explanation:
The student's question about Kelli buying pajamas cannot be answered without the accompanying graph mentioned. Without information on the pricing and the quantity discounts (if any) from the graph, it is not possible to determine the correct amount it would cost Kelli to buy a sixth pair of pajamas for herself. Since the question seems to be about linear relationships or unit pricing, which are typically mathematical concepts involving the calculation of costs based on given rates, this falls under the subject of Mathematics.
However, regarding the set of problems provided about Marie and her weekly budget for magazines and pies, the following answers can be given:
- The maximum number of magazines Marie could buy at $4 each with a $24 budget is 6 magazines.
- With each pie priced at $12, the maximum number of pies she could buy in a week is 2 pies.
For the question about Jade's opportunity cost of purchasing a pie, it is represented by the number of magazines she must give up to purchase one pie. Since one pie costs $12, and one magazine costs $4, Jade would have to give up 3 magazines for each pie, because $12 divided by $4 equals 3.
To determine how much it will cost Kelli to buy a sixth pair of pajamas for herself, we need to look at the graph given. The graph shows the number of pairs of pajamas and their corresponding cost. According to the graph, buying the sixth pair of pajamas would cost $80.00, which is Option 3.
