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 mark
up 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?
4g+3(-3+4g)=1-g Distribute the 3(-3+4g) 4g-9+12g=1-g Add 4g and 12g 16g-9=1-1g Add 1g and 16g (variables always have an invisible 1 in front) 17g-9=1 Add 9 and 1 17g=10 Divide both sides by 17 and the answer is g=10/17
