Explanation:
If Barry's utility from consuming a used novel is 32 utils and the book costs $4, he was able to get 8 utils per dollar (= 32 / $4).
If an audio book costs $8, then Barry should obtain $8 x 8 utils per dollar = 64 utils. 
 
        
             
        
        
        
The negative relationship between the quantity of a good, service, or resource and the marginal utility obtained from each additional unit consumed in a given period of time describes diminishing marginal utility.
<h3>What is  
diminishing marginal utility?</h3>
Marginal utility is the increase in utility as consumption is increased by one unit. 
According to the law of diminishing marginal utility, as more of a product is consumed, utility increases at a diminishing rate. Economic theory suggest that consumption is maximised when marginal utility is equal to marginal revenue.

Answer: RM3
Explanation:
Gross domestic product has to do with the monetary value of the goods that are produced in a particular economy. In this case, the total contribution will be RM3 since it's the final amount that the bread is sold.
It should be noted that RM2 in this case is the intermediate good and should therefore bit be included so that there won't be an overstatement of the GDP and to prevent double counting.
