Rewrite the percentage as a decimal and multiply it by her pay.
3.5%= 0.035
8000 x 0.035 = $280.00
4x + 2y = 20 in slope intercept form would be y = 2x + 10
300.50 + 0.07x > = 900.85
0.07x > = 900.85 - 300.50
0.07x > = 600.35
x > = 600.35 / 0.07
x > = 8576.43 <=== she would have to sell at least 8576.43
