It will take 100 weeks to build the tower.
Since Donald Trump wants to build a 100 meter high tower as quickly as possible with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall, and using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are, to determine what is the shortest amount of time (weeks) that it will take to build the tower, the following calculation must be performed:
- Time per block x total blocks = Total time
- 1 week x 100 = X
- 100 weeks = X
Therefore, it will take 100 weeks to build the tower.

81. Each apple cost $0.50
82. One pound of chocolate = $3
Step-by-step explanation:

Let sold of 1 senior citizen ticket be "s", and
cost of 1 child ticket be "c"
First Day, 4 senior citizen ticket and 5 child tickets sold, equaled $46, so the equation we can write is:
Second Day, 3 senior citizen ticket and 1 child ticket sold, equaled $22, so the equation we can write is:
So, the system of equation (2 equations) written above can be solved simultaneously to find our answer.
81.
Let price of 1 apple be "a" and price of 1 banana be "b"
Since 3 apples and 2 banana cost $2, so we can write:
3a + 2b = 2
Then,
4 apples and 4 bananas cost $3, so we can write:
4a + 4b = 3
We can solve for the variable b in equation 1. Shown below:
Now we put this value of b into equation 2 and solve for cost of 1 apple, a. Shown below:
So each apples cost $0.5
82.
Let 1 pound of chocolate be cost "c"
Let 1 pound of peanut be cost "p"
4 lb of chocolate and 2 lb of peanut = $16, thus we can write:
4c + 2p = 16
Next,
2 lb of chocolate and 3 lb of peanut costed $12, so we can write:
2c + 3p = 12
We solve first equation for p:
Now, we put this expression for p into equation 2 and solve for c:
So, 1 pound of chocolates cost $3
