Sharon makes headbands and sells them online. She is analyzing the sales of two of her most popular styles, For style A, she sold 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

the answer is c: s=40(1.1)^m, s=20(1.15)^m

Step-by-step explanation:

in option A, (0.10) and (0.15) make it exponential decay rather than exponential growth like it's supposed to be.

In option B, the rate of growth is supposed to be on the exponent, not the sales themselves in the equation

option c is correct I just finished the test

option d has the same mistake as a and b combined

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
