The prompt provides a graph-related question about Sandi's demand and asks for marginal revenue when output rises from 44 to 55 cards, but there are no answer choices or numeric data given in the provided content.

First, recall how to compute marginal revenue: MR from increasing output by ΔQ is MR = ΔTR / ΔQ, where TR = Price × Quantity. To find TR at Q = 44 and Q = 55, you need the corresponding prices P(44) and P(55) from the demand curve shown in the graph.

Since the graph itself (the price at Q = 44, and the price at Q = 55) is not included in the text you provided, we cannot determine the exact TR values for these quantities. Without TR at both points, ΔTR cannot be computed, and thus MR cannot be determined.

What you would do if you had the graph:
- Identify the price on the demand curve when quantity is 44 cards per week. This gives P(44).
- Identify the price on the demand curve when quantity is 55 cards per week. This gives P(55).
- Compute total revenues: TR(44) = 44 × P(44) and TR(55) = 55 × P(55).
- Compute ΔTR = TR(55) − TR(44).
- Compute MR = ΔTR ÷ (55 − 44) = ΔTR ÷ 11.

If the graph shows a downward-sloping demand curve, MR can be positive or negative depending on whether TR increases or decreases with the output step; typically MR falls as output increases, and with discrete steps such as from 44 to 55, you’d evaluate whether TR rose or fell over that interval.

Bottom line: there isn’t enough information in the provided text to produce a numeric marginal revenue. If you can share the prices from the graph at Q = 44 and Q = 55, I can compute MR step by step. If the intent is to practice the method, remember to extract P at each Q from the graph, compute TR values, find the difference, and divide by the change in quantity (11 cards).
