A members-only speaker series allows people to join for $19 and then pay $4 for every event attended. What is the maximum number of events someone can attend for a total
cost of $31

3

Step-by-step explanation:

Let's create a model first.

The initial fee is $19 (this is our y intercept or b)

And the pay per is $4 (this is our variable or m)

y=mx+b

y= 4x+19

To find out what the maximum number of events someone can attend for $31, we plug in different number for the x value until it's less than or equal to $31

In this case, plugging in 3 for x gives us exactly $31

y=4(3)+19= 31

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

x/3-10=8

x/3=18

x=48
