A stray dog ate 12 of your muffins. That was 3/10 of them! With how many did you start?
0.3x = 12
x = 40
To determine the original number of muffins you had, we can use the given information that 3/10 of them were eaten. By setting up a proportion, we can find the answer.
Let's assume that x represents the original number of muffins you had. Setting up the proportion, we have:
(3/10) = 12/x
To solve for x, we'll cross-multiply:
3x = 12 * 10
3x = 120
Now, divide both sides of the equation by 3 to isolate x:
x = 120 / 3
x = 40
So, you originally had 40 muffins before the stray dog ate 12 of them.
