I must assume that you meant "sqrt(191)."
What's the first perfect square greater than 191? Answer: 196 = 14^2
What's the first perfect square smaller than 191? Answer: 169 = 13^2
Note how 169 < 191 < 196. Thus, the square root of 191 lies between 13 and 14.

Answer:
p = (7r+16) / (4-q)
Step-by-step explanation:
4p - 7r = pq + 16
Add 7r to both sides.
4p = pq + 16 + 7r
Subtract pq from both sides.
4p - pq = 7r + 16
Factor out p from the left side.
p(4 - q) = 7r + 16
Divide both sides by (4 - q).
p = (7r + 16)/(4 - q)
The 7r and the 16 could be in either order, like 7r+16 or 16+7r. You could show that the answer is a fraction with 7r+16 on top and 4-q on the bottom. If you are writing or on the computer selecting a fraction that is stacked you don't need need the parenthesis.
The correct answer is A $4.28 x 4 = $19.28
