Lets begin with an example.
You have 100 apples. 40 % of your apples are 40. Sounds complicated?
Here is the calculation in words, number of apples times 40 percentage.
By equation: 100 * 40/100= 40. Simple huh?
% symbol represents 100.
% 15 equals 15/100; 20% is equal to 20/100 or 1/5 in a simplified way.
Have a look to question. 40 iris at last year, 15 % MORE iris this year.
What is the 15 % of 40 iris? That's the question at the end.
Recall apple example at the beginning.
40 iris * 15/100 = 6.
So, there are 6 MORE iris blooms this year. This year Savanna has totally 46 iris.
Using the Fundamental Counting Theorem, there are 60 different ways to order the pizza.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

For this problem, the parameters are found as follows:
- For the sauce, there are 2 options, cheese or tomato, hence
.
- For the topping, there are 4 options, but the options may be combined, for example, Pepperoni and Sausage, hence
.
- The topping can be added to either all the pizza or only half the pizza, hence
.
Thus the number of ways is given by:
N = 2 x 15 x 2 = 60.

225 miles / 3 hours = 75 miles / 1 hour
so the rate per hour is 75 miles
Q - 756 = 612 |add 756 to both sides
Q - 756 + 756 = 612 + 756
Q = 1368
Answer: y=-2x+3
Step-by-step explanation:
M= 1--2/-1-5
Y-1=-2(x-1)
-2x+2+1
Y=-2x+3
