Answer:

$122.72  (Aprox)

Step-by-step explanation:

1 ft = 12 inches

2 inches = 2/12 = 0.166667 ft

then:

9ft 2 in = 9.166667 ft

Proportions:

9.1666667 ft ⇒ $15

75 ft ⇒ $A

A = 75ft * $15 / 9.1666667ft

A = $122.72 (Aprox.)

Answer: 120 (Rounded) or 122.7 (Non-Rounded)

Step-by-step explanation:

To start off, let's convert the 9 feet 2 inches and 75 feet into equivalent numbers. 9 feet 2 inches is 110 inches (Since 9 times 12 is 108, and add the 2 and you get 110) , and 75 feet is 900 inches. (75 times 12, since 12 inches are in a foot). If 110 is $15, and 900 is an unknown, we can take a look at the two in this way:

15/110=?/900

To find our answer, let's start by dividing 900 by 110; this equals about 8.18

So now we can take the 15 and multiply by 8.18.

Now this makes our fractions equivalent and gives us our answer of 122.7

Now, if 8.18 is rounded, consider your answer 120

(I can't give a definite answer other than 122.7 or 120 since this isn't multiple choice so I can't tell to round or not.)

Hope this helps!
