Answer: <em>Please note the number of the order may differ.</em>

n_1  = 18

n_2 = 9

Step-by-step explanation:

     We will write mathematical equations to represent the situation. Let n_1 be the first number and n_2 be the second.

-> The sum of two numbers is 27.

n_1 + n_2 = 27

-> One number is 2 times as large as the other.

n_1  = 2 * n_2

     Now, we will solve it as a system of equations.

n_1 + n_2 = 27

(2 * n_2) + n_2 = 27

3 * n_2 = 27

n_2 = 9

-----------

n_1  = 2 * n_2

n_1  = 2 * (9)

n_1  = 18

Papessa [141]

we know that

by proportion

\frac{18,000}{900} \frac{\$}{feet}= \frac{x}{60}\frac{\$}{feet} \\\\ 900*x=18,000*60 \\\\x= \frac{18,000*60}{900}\\\\ x= \$1,200

therefore

<u>the answer is</u>

\$1,200
