## Algebra 2 (1st Edition)

Choice B is correct: $\frac{ 9.50 - 8.40}{9.5} \approx 0.12 = 12$ percent $\frac{ 8.40 - 7.40}{8.40} \approx 0.12 = 12$ percent $\frac{ 7.40 - 6.50}{7.40} \approx 0.12 = 12$ percent $\frac{ 6.50 - 5.70}{6.50} \approx 0.12 = 12$ percent Thus, there's about a 12% savings with each additional increase of 50 shirts ordered.
