Answer:
128 posibilities
Step-by-step explanation:
We have 7 colleges (A,B,C,...,H) which form a set with seven elements.
What you are asking is the number of elements (or cardinality) of the set that contains all possible sets formed by those 7 elements (or the "power set").
It is known that if n is the number of elements of a given set X, then the cardinality of the power set is
.
Therefore, there are
or 128 possibilities (or elements) for the set of colleges that he applies to.
So,
"double 2"
2(2)
"add 5"
+ 5
Therefore, the whole expression would be:
2(2) + 5
If you wanted to evaluate it, it would come out like this.
4 + 5

Answer:
A family paid $19,800 as a down payment for a home. If this represents 12% of the price of the home, find the price of the home.
----------------
Let the price of the home be "x":
Equation:
0.12x = 19800
x = 19800/0.12
----------------
x = $165,000
