The answer I believe is Dependent
First, note that
1 yard = 3 foot,
1 feet = 12 inches.
Now add all lengths:
15 ft 4 in + 9 ft 2 in + 14 ft 7 in + 10 ft 11 in +5 ft 8 in = 53 ft 32 in.
Since 32 in = 24 in + 8 in = 2 ft 8 in, then
53 ft 32 in = 53 ft + 2 ft 8 in =55 ft 8 in.
Since 55 ft = 54 ft + 1 ft = 18 yd 1 ft, then
55 ft 8 in = 18 yd 1 ft 8 in.
Answer: correct choice C
Use a long division method to solve this question.
I hope you know how to use this method.

Answer:
a) 5<x<25
b) x≤5 or x≥25
c) x≥5 and x≤25
Step-by-step explanation:
Given the expression the
(x - 5) (50 - 2x) to represent sofie profit based on the price per scarf, x.
a) If Sofie's profit is increasing, them the expression for her profit must be greater than zero as shown.
(x - 5) (50 - 2x)> 0
Solving the inequality:
x-5>0 and 50-2x>0
If x-5>0
x > 5 or 5<x... (1)
Similarly when 50-2x>0
50-2x>0
50>2x
Dividing both sides by 2:
50/2>2x/2
25>x or x<25 ...(2)
Combining 1 and 2
5<x<25
b) if Sofie's profit is decreasing, the profit function must be less than or equal to zero as shown;
(x - 5) (50 - 2x)≤0
Solving the inequality
x-5≤0 and 50-2x≤0
x≤5 and 50≤2x
x≤5 or 25≤x
x≤5 or x≥25
c) If Sofia is not making profit then, the function (x - 5) (50 - 2x) is equal to zero i.e
(x - 5) (50 - 2x) = 0
x - 5 = 0 or 50-2x =0
x = 5 and 50 = 2x
x = 5 and x = 25
x≥5 and x≤25
