Formula: total = principal x (1 + (interest rate x loan time))
total = 1000 x (1 + (0.055 x 2))
total = 1000 x (1 + 0.11)
total = 1000 x 1.11
total = $1110

Graph the equation and see where the highest point on the graph is. The x coordinate is the price and the y coordinate is the profit.
(x+1)(x-4)-(x-2) = 0
x²-4x+x-4-x+2 = 0
x²-4x-2 = 0
/\ = (-4)² - 4*1*(-2)
/\ = 16 + 8
/\ = 24
x = (-(-4)+/- \/24) / 2
x = (4+/-\/4*6)/2
x = (4+/-2\/6)/2
x = 2+/-\/6
x' = 2+\/6
x" = 2-\/6
