Answer:
The opportunity cost would be $240k
Explanation:
The college fee per year is $30k plus expenses. After 4 years, you will be out $120k. The opportunity cost in this case will be $240k since you chose to go to college instead of working. Thus, you will earn less or no money during the years that you are in college.

Tina solved 15 hard puzzles.
We can use the system of equations:
X represents the easy puzzles
Y represents the hard puzzles
x+y=50
3x+6y=195 (I just divided everything by 10 to make things easier)
Then I multiplied the first equation by -3 to be able to cross out x and solve for y.
So now we have -3x-3y=-150.
Now we can add the equations together and we get:
-3x-3y=-150
3x+6y=195
+________
3y= 45
y=15.
That means that Tina solved 15 hard puzzles and 45 easy puzzles.

The explicit rule for this geometric sequence 29,23,2,6, is n = 29 × (29/23)^(n - 1)
<h3>How to write explicit rule</h3>
Second term, a×r = 23
23 = 29 × r
23 = 29r
r = 29/23
The explicit formula is given by
nth term = ar^(n - 1)
n = 29 × (29/23)^(n - 1)
Where,
nth term = number of terms
