y1 = 500 + .04x
y2 = 400 + .05x
500 + .04x = 400 + .05x Subtract 400 from each side of the equation.
100 + .04x = .05x Subtract .04x from each side of the equation.
100 = .01x Divide both sides of the equation by .01.
10,000 = x Kenisha needs to sell $10,000 of athletic shoes for the two pay plans to pay the same amount.
For sales under $10,000, the $500 base plan is the better plan. For sales over $10,00, the $400 base plan will result in a larger paycheck.
