Answer:
Total variable cost= 90,000
Total fixed costs= 8,000
Total costs= $98,000
Explanation:
Giving the following information:
Production of 15,000 units:
Fixed costs= $8,000
Total variable cost= $75,000
We have no reason to believe that the fixed costs will change. If 18,000 units remain in the relevant range, the fixed costs are constant.
<u>We need to calculate the unitary variable cost:</u>
Unitary variable cost= 75,000/15,000= $5
Now, for 18,000 units:
Total variable cost= 5*18,000= 90,000
Total fixed costs= 8,000
Total costs= $98,000
Answer:
The correct answer is option d.
Explanation:
The most effective model to understand the effect of change of a variable on other variable is by assuming other factors to be constant. This simplifies the model and helps in easily understanding the relationship between the two variables.
Though the assumption of other things being constant does not apply in the real world, it is still used as otherwise change in other factors would complicate the model. If several factors change it would be difficult to understand the relationship between variables.
Here, to study the effect of change in the price of grapes on the market for wine, it is necessary to assume other factors such as income, consumer preferences, etc to be constant.
