At the amusement park, laura paid $6.00 for a small cotton candy. her older brother works at the park, and he told her they markup the cotton candy by 300%. laura does not think this is mathematically possible. is it possible, and if so, what is the price of the cotton candy before the markup?

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
