Question

An animal shelter estimates that it costs about $6 per day to care for each dog. If y represents the total cost of caring for a single dog for x days, which table models the situation?

Answer 1

Answer:

Step-by-step explanation:

If it costs 6 dollars per day, that means that the cost/day=6, or that the total cost divided by the amount of days equals 6. Since cost is y and days is x, we have y/x=6. Multiplying both sides by 6, we have y=6x. Plugging that into each table, we can see that the last table fits the description, with y*6=36, 9*6=54, and 12*6=72.

Answer 2

Answer:

x     y

6     36

9     54

12    72

Step-by-step explanation:

The options are shown in the pictures attached.

Data:

a single dog costs about $6 per day

y-variable represents the total cost

x-variable represents days

So, 1 day costs $6, 2 days costs 2*$6 = $12, 3 days costs 3*$6 = $18 and so on. Then, the table is:

x     y

6     6*6 = 36

9     9*6 = 54

12    12*6 = 72
