Answer:

4 more pens

Step-by-step explanation:

Well, what do we know?

We know Sheila has:

6 pens

10 pencils

How many MORE pens does she need to make the number of pens <em>equal to </em>the number of pencils?

6 + x (x is the number of pens needed to EQUAL to 10)

6 + x = 10

x = 4

Sanity check:

6 + 4 = 10

Sheila needs 4 more pens to make the number of pens and pencils equivalent, or EQUAL TO each other.

Cupcakes didn't have sprinkles = 35

Total cupcakes = 15+35 = 50

The percentage of the cupcakes had sprinkles = \dfrac{\text{Cupcakes have sprinkles}}{\text{Total cupcakes}}\times100
