Answer 1

the total amount of compost Annie gets is 12 every day
c equals 12 every d
c = 12d

Answer 2

Function will be c = 12d.

Explanation:

Annie has a compost pile that produces 12 pounds of compost every day from yard waste.

Now we can get the compost as given in the table.

Days 1 2 3 4

Amount of compost(c) 12 24 36 48

Here we see the table is an arithmetic series.

If the amount of compost is c and number of days as d . Therefore the relation between c and d is

c = 12d
