15% x
100 1.15 X is your variable, your unknown number and 15% has to always be over 100 , Then you have to cross multiply and divide 100 because that is the only number basically you have to just multiply across and divide 100 to make it to the nearest cent you have to round the last two numbers after the decimal Representing money.. Hope this helps!!

For this case we must construct a system of two equations with two variables. Let "h" be the number of hardcover version books, and let "p" be the number of paperback version books. If the hardcover version of a book weighs 7 ounces and the paperback version weighs 5 ounces, to reach a total of 249 ounces we have:
(1)
On the other hand, if there are Forty-five copies of the book then:
(2)
If from (2) we clear the number of books paperback version we have:

As each paperback version book weighs 5 ounces, to obtain the total weight of the paperback version books, represented by "x" in the table shown, we multiply
So, 
Answer:

Option D
<h2>
P is equal to:</h2>
48.
Because 46+48 equals 94.
You can easily find out equations to this by subtracting the 46 from 94 to see what p is equal to.

Probability of rolling a number greater than 3:
P ( A ) = m/n
m =3, (numbers 4, 5, 6)
n = 6, (numbers 1 to 6).
P ( A ) = 3/6 = 1/2 = 0.5
