Answer:
10% of 440.00=44
1%(÷by 100) of 440.00=4.40
1%=4.40
then do 44+4.40+4.40=52.80(that is 12% comission)
then you add 12% of 440 onto his weekly salary that equals to 492.8
this week he sold 525.000
12%of 525.00=63
then add 63 to 440=503
so Rany eartn $503
?
12(2)+5
Dang, you're an elementary school er? Good grief i'm and 8th grade math one student!
Answer:
234 books.
Step-by-step explanation:
You need to set up a proportion. Be careful to note what it looks like and the explanation that follows.
9 books 13 magazines
======= = ===========
x 572 - x Cross multiply
What you want is the number of book sales from the proportion.
However all you have is the ratio of books to magazines. So you have to set up the total sales to magazines, which is a bit awkward. 572 - x is the number of magazine sales.
9*(572 - x) = 13x Remove the brackets on the left.
5148- 9x = 13x Add 9x to both sides.
5148 = 13x + 9x Transpose and add the right.
22x = 5148 Divide by 22
x = 5148/22
x = 234
234 books were sold.
Answer:
The answer is: C. 3my^4 - 3my^2x
Step-by-step explanation:
For the problem:
3my^2 (y^2x - x) =
Multiply each term by 3my^2:
3my^2 * y^2x - 3my^2 *x =
3my^4x - 3my^2x
