The total cost for this certain activity level can be calculated by substituting 4000 to the x of the equation given above,
                          y = 7000 + 1.8(4000)
                          y = 14200
Thus, the total cost of the activity level is $14,200.

Explanation:
 As most students discover, college is not the same as high school. For many students, college is the first time they are “on their own” in an environment filled with opportunity. And while this can be exciting, you may find that social opportunities conflict with academic expectations. For example, a free day before an exam, if not wisely spent, can spell trouble for doing well on the exam. It is easy to fall behind when there are so many choices and freedoms.
One of the main goals of a college education is learning how to learn. In this chapter we zoom in on learning how to skillfully manage your time. To be successful in college, it’s imperative to be able to effectively manage your time.

Answer: $100
Explanation:
Opportunity cost is the benefit that we forgo when another option is chosen thereby leaving out something else. Based on the information given, Ed's opportunity cost of going to the ball will be calculated as the addition of the income that's lost when he takes some time off from his work and the expenses that he incurs on the base ball game. This will be:
= ( 4 × $15) + $25 + $15
= $60 + $40
= $100
The opportunity cost is $100.
