The monthly cost to stream movies depends on the number of movies, m streamed. Which inequality represents the situation when the monthly cost at Company A is less than the monthly cost at Company B?

A) 3m + 4 > 9m
B) 3m + 9 < 4m
C) 3m + 9 > 4m
D) 3m + 4 < 9m

Answer 1

The answer is letter B

Answer 2

Answer: B) 3m + 9 < 4m

Explanation:

Hi, to answer this question we have to write an equation for the total cost of each case using the information given:

Company A: To obtain the total cost at company A we have to multiply the number of movies streamed (m ) by the cost of each movie (3) and add the monthly fee(9)

A=3 m+ 9

Where m is the number of movies streamed.

Company B:

B= 4m

If the monthly cost at Company A is less than the monthly cost at Company B, it means that the cost at company B Is more than the cost at company A.

3m+9 <4m
