Let d be the amount of dirt in pounds.
Let t be the number of minutes dirt has been added.

d(t) = 300 + 25t

Denis pretty much covered your question. I can stress declaring your variables, teachers are picky about it.

Let t be the number of minutes dirt has been added.

d(t) = 300 + 25t

User Funny did declare the variables, except he/she is missing the needed "in pounds" for D.

And Funny used capital letters instead of lower case letters.

Funny, based on what you gave, your equation could be:


D = 25T + 300 \(\displaystyle \ \ \ \ \)or

D = 300 + 25T
