The Brown's are renting a home and are planning to set up their trash service. They are considering two local companies. Company A charges a $50 setup fee and $15 per month. This can be represented by the linear function C = 15x + 50. Company B charges $100 for the setup fee and $12 per month. This can be represented by the linear function C = 12x + 100. They are planning to rent their home and use trash service for 6 months. Which statement is true?
A) The cost of using Company B is the same as the cost of using Company A.
B) The cost of using Company B is $32 less than the cost of using Company A.
C) The cost of using Company A is $32 less than the cost of using Company B.
D) The cost of using Company B is $18 less than the cost of using Company A.
Eliminate
The answer is C. You will plug in 6 for the X value in the equations because they are going to use it for six months. c= A.15(6) + 50 and B.c=12(6) +100. solving those out A will be $140 and B will be $172.
