Answer:
In 2 months, that cost is $80
Step-by-step explanation:
Option 1: after 2 months they will have paid 40 for set-up and 20*2 for cost per month so 40 + 40 = 80
Option 2: after 2 months they will have paid 0 for set-up and 40*2 for cost per month so 0 + 80 = 80
Answer:
2, 80
Step-by-step explanation:
The situation can be represented by 40 + 20x = 40x.
You need to find the x value that makes this equation true (x will represent the number of months).
40 + 20x = 40x
40 + 20x - 20x = 40x - 20x
40 = 20x
x = 2
It will be in 2 months.
40 + 20 (2) = 80.
80 is the cost.
