The fоllоwing tаble shоws the totаl benefit, in dollаrs, that Carlos receives from consuming two goods, sodas and candy bars. Table: Carlos’s Total Benefit Schedule for Sodas and Candy Bars Quantity of Sodas Total Benefit of Sodas Quantity of Candy Bars Total Benefit of Candy Bars 0 $0 0 $0 1 $40 1 $80 2 $70 2 $120 3 $90 3 $140 4 $100 4 $152 5 $103 5 $156 6 $105 6 $156   Carlos has a limited weekly income of $20, and he spends it all on candy bars and soda. Assume the price of each soda is $2 and each candy bar is $4. Identify the quantity of candy bars and sodas that will maximize Carlos’s total benefit given his weekly income. Explain using marginal analysis. (3 points) Calculate the consumer surplus from the fourth candy bar. Show your work. (3 points) If Carlos’s weekly income decreases from $20 to $18, would Carlos be able to buy 5 sodas and 2 candy bars? Explain your answer. (3 points) Suppose that candy bars are produced in a perfectly competitive market, and the price of sugar, an input for producing candy bars, increases. If candy bars are a normal good, will the quantity of candy bars that will maximize Carlos’s total benefit increase, decrease, or stay the same? Explain. (3 points) Now suppose that instead the price of sodas increased by 10% and Carlos buys 6% fewer sodas and 3% less of Good B. Based on this change, state whether sodas and Good B are substitutes, complements, inferior, or normal goods. Explain using numbers. (3 points)
