Ms sullivan bought some pens at the school supply store, including 5 red pens. 25% of all the pens she brought were red.

Respuesta :

Answer:

20 pens

Step-by-step explanation:

Note : I am assuming that the question is asking for all no. of total pens.

If 5 red pens were 25% of the total quantity, we can say that 1/4th of the pens were red.

If 5 pens = 1/4, we multiply 5 * 4 to find the total quantity. 5*4 = 20

So, Ms. Sullivan bought 20 pens.

Hope this helps!
