Quizplus · Accepted Answer

The marginal benefit of the sixth unit of chocolate is -1. This means that the additional benefit Jenny receives from consuming the sixth unit of chocolate is less than the cost of that unit. Therefore, the total benefit derived from the sixth unit of chocolate is negative. To find the total benefit, we need to subtract the total benefit derived from consuming five units of chocolate from the total benefit derived from consuming six units of chocolate.
Total Benefit from consuming 5 units of chocolate = $28
Total Benefit from consuming 6 units of chocolate = $27
Therefore, the total benefit derived from the sixth unit of chocolate is ($27 - $28) = -$1.
This implies that the best choice for Jenny is to consume only five units of chocolate, as consuming the sixth unit of chocolate would decrease her total benefit.
