A stray dog ate 6 of your muffins. That was four thirds of all of them. With how many did you you start?

Answer 1

Answer:

Step-by-step explanation:

The total number of muffins was  

40

.

Explanation:

You can translate the important parts of the sentence from English to math (say that  

n

is the total number of muffins):

A stray dog ate  

6



6o f your muffins.

 

=



That was

3

10

×



of

 

n



all of them!

Now copy down the equation and solve for  

n

:
