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

Answer:

5 months

Step-by-step 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

$m = \frac{50}{10}$

$m = 5$
