Question

Suppose c was a total membership cost for m the two equations that model c are c=30m+50 an c=20m+100

Answer 1

5 months

Explanation:

Given

`c = 30m + 50`

`c = 20m + 100`

Required [Missing from the question]

At what month will the cost be equal

To do this, we equate both expressions

`c = c`

This gives:

`30m + 50 = 20m + 100`

Collect like terms

`30m - 20m = 100 - 50`

`10m = 50\\`

Solve for m

`m = (50)/(10)`

`m = 5`
