300 dollars, 15x20 because they count any fraction as a foot, so is like you are going to buy 20 foot of carpet.
2160
Explanation:
Use the equation (n-2)180
(14-2)180
(12)180
2160
7/8 = x/48
Cross multiply, which is: a/b = c/d ⇒ ad = bc
After cross multiplying, we get:
8x = 7(48)
8x = 336
Divide 8 on both sides
x = 42
Your final answer is B. 42<span>.</span>
