Steve trades in his 99-hp subcompact car for a 700-hp muscle car. Both cars run on gasoline, a fossil fuel. What differences can Steve expect as he starts driving his new car

lower fuel efficiency, higher top speed, and quicker acceleration

Explanation:

Since we have to compare the differences at the time of driving a new car. The differences could be that in the case of high efficiency car the efficiency of the fuel is less but if we talk about the speed and the acceleration part so it would be fast and quicker too

Therefore as per the given options, the last option is correct and the same is to be considered

answer: marginal utility of the fourth brownie is 0.

explanation: marginal utility is the addtional utility gained from the consumption of one more unit of a good. it is given by,

so, marginal utility at the 4th unit will be given by

since, the values are not given here, you can simply find marginal utility at fourth unit by subtracting total utility at 3rd unit from total utility at 4th unit.
