Dwight wants to buy a camera that is on sale for 25% off. The original price of the camera is $300. What is the amount of the discount? Define a variable, write an equation and solve algebraically.

The expected solution is a division equation

Why is a multiplication equation an incorrect solution ? Let d = amount of discount;

d = 0.25 x 300

Would greatly appreciate your reply.

    $\begingroup$ I mean, that's fine too...unless your teacher specifically wanted in the form of some division. $\endgroup$ – Don Thousand Jan 23 '19 at 23:26
  • $\begingroup$ Nothing wrong with that. Don't know how to do it by division. $\endgroup$ – fleablood Jan 23 '19 at 23:38

Your answer is correct. Any multiplication statement can be rewritten as a division equation:

$$d=0.25 \times 300 = \frac{1}{4}\times 300 = \frac{300}{4}$$
