Arrange the following steps in the process of determining consumer surplus using marginal analysis: 1) Assess the price a consumer is willing to pay, 2) Compare the marginal benefit with the market price, 3) Calculate the consumer surplus, 4) Determine the optimal quantity to purchase.

To determine consumer surplus using marginal analysis, start by assessing the price a consumer is willing to pay for a good or service. This is important because it reflects the maximum value they place on that item. Next, compare this marginal benefit with the market price to see if the consumer gains value from purchasing the item. After that, determine the optimal quantity to purchase, which is the amount where the consumer feels they get the most benefit. Finally, calculate the consumer surplus, which is the difference between the price they were willing to pay and the market price for the quantity they decided to buy.
