Sharon makes headbands and sells them online. She is analyzing the sales of two of her most popular styles, For style A, she sol
d 40 in the first month and had a 10% increase in sales each month after that. For style B, she sold 20 in the first month and had a 15% increase in sales each month after that. Which system of equations can she use to determine the number of months, m, until the sales, s, are the same for both headband styles?
A. s = 40(0.10)^m, s = 20(0.15)^m B. s = 1.1(40)^m, s = 1.15 (20)^m C. s = 40(1.1)^m, s = 20(1.15)^m D. s = 10(40)^m, s = 15(20)^m
