Answer:
$4.25
Step-by-step explanation:
4 quarters is 1 dollar
1 nickel is 5 cent
14 divided by 4 = 3.5
3.5 + 5 times 5 = $4.25
Answer:
3.825
Step-by-step explanation:
First, you have to move the decimal two over on 45%. If you move the decimal over two spaces to the right, it would be 0.45. In math, of means to multiply, so then you multiply 0.45 and 8.5 to get your answer of 3.825.
Division Problem: 90 people were invited to the party.
1. How many tables are needed, if each table can seat 8 people?
2. How many tables will be completely full?
3. How many people will be at an incomplete table?
Solution:
You have that 90=8·11+2 (8 - divisor, 11 - quotient, 2 - remainder).
Since the quotient is 11, 12 tables are needed, 11 tables will be completely full and the last 12th table will be incomplete, only 2 people will be at this table.
Answer: 1. 12 tables, 2. 11 tables, 3. 2 people

Answer: 120</h3>
===================================================
Explanation:
There are 5 choices for the first selection, 4 choices for the second, etc etc until we reach 1 for the last selection. We have the countdown {5,4,3,2,1}. We'll multiply those values together to get our answer.
5*4*3*2*1 = 120
This operation of starting with some integer, counting down and multiplying along the way, is done so very often that it's given a name which is "factorial". The shorthand notation is to use an exclamation mark. So we'd say 5! = 120
