180/3 = 60

y = 60x

Answer:

Step-by-step explanation:

Let x represent the monthly cost of

Mr.Greene's wireless phone.

Let y represent the total cost for x months

Mr.Greene's wireless phone bill, 3 months costs $180. This means that

1 month would cos 180/3 = 60

For 9 months, his Bill was $540. This means that

1 month would cos 540/9 = 60

The equation that best represents the relationship between the amount of months (x) and total cost (y) is

y = 60x
