The solution is r= 7/a-x How did i do this?
Your equation is ax+ r=7, so the goal is to isolate the r. You begin by dividing the a from the ax. Remember, what you do to one side, you must do to the other. So you do 7/a, since you can't simplify 7/a, leave it as it is. Next, your equation should look like this x+r=7/a. In order to isolate the r, you move the x to the other side by subtracting, which leaves you with the answer of r= 7/a-x.
Hope this helped!

Answer:
Option A) is correct.
Step-by-step explanation:
The final cost of a sale item is determined by multiplying the price on the tag by 75%.
So. if the final cost is represented by $F and the price on the tag is $t, then the relation between F and t will be
F = 0.75t.
This relation is linear since the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
Therefore, option A) is correct. (Answer)
