Order of operations (PEMDAS):
21 - 18 <span>/ 3 * 2
let's add some parenthesese to make it easier to see:
21 - (18 / 3 * 2)
multiplication and division are associative
also: 18 / 3 = 18 * (1/3)
21 - (18 * (1/3) * 2)
21 - (6*2) or 21 - (36 * (1/3)) or 21 - (18 * (2/3))
21 - 12

Ok don't panic!!!
First you look and see that 3 dozen is 36 and you need 720 cookies so that every person gets 2 cookies. so you first need to multiply 36 by 10 to get 360 then multiply that by 2.
So, in conclusion multipy each of the ingredients by 20! :)
17/16 x 20 = 340/16 of butter
5/8 x 20 = 100/8 of white sugar
7/4 x 20 = 140/4 of vanilla extract
15/8 x 20 = 300/8 of flour
5/6 x 20 = 100/6 of almonds
7/12 x 20 = 140/12 of confectioner's sugar

Answer:
Pop in 1990 = 81 million rats
Pop in 2005 = 127 million rats
Step-by-step explanation:
Given the function, the population of rats in 1990 is when we replace t with "0" which strictly gives the coefficient 81 that represents 81 million rats.
The rat population in 2005 is given by the formula when t = 15
This is: approximately 127 million rats.
