please can you provide explanation the relationship MRS and the marginal utility

1. Suppose Michael purchases only two goods, hamburgers (H) and Cokes (C). (a) What is the relationship between MRSHp and the marginal utilities M U H and MUG 5' (b) Draw a typical indierence curve for the case in which the marginal utilities of both goods are positive and the marginal rate of substitution of hamburgers for Cokes is diminishing. Using your graph, explain the relationship between the indifference curve and the marginal rate of substitution of hamburgers for Cakes. (c) Suppose the marginal rate of substitution of hamburgers for Cokes is constant. In this case, are hamburgers and Cokes perfect substitutes or perfeat complements? (d) Suppose that Michael always wants two hamburgers along with everyr Coke. Draw a typi- cal indifference curve. In this case, are hamburgers and Cakes perfect substitutes or perfect complements
