G. $m=36d+28,000$

Work Step by Step

We want the equation to tell us the total number of miles, m, so we know that the m should be alone on one side of the equal sign. This leaves us one answer--G. We double check that this is the correct answer by looking on the right side of the equation. d, the number of days she drives, is multiplied by 36, which we know is correct because she drives 36 miles per day. 28,000 is added to this number, which we also know must be done as the car starts with 28,000 miles on it.
