No. of pencils bought

= 24÷2 --> written as an equation

= 12

Answer 2

Answer:

Equation: 24 - 2p = 10

Pencils she bought: 7 pencils

Explanation:

Let number of pencils be p

initial money - cost of pens = final money

24 - 2p = 10

-2p = 10 -24

-2p = -14

p = 7

So she bought 7 pencils in total.
