Question

Alex has a box of pens and pencils. Of all his pens and pencils,

1
4
of them are pens. He has
57
pencils.

Part A
Create an equation to represent the total number of pens and pencils,
p
, Alex has.

Answer 1

a. p = n + m

where: n is the number of pens, and m is the number of pencils

b. p = 71

Explanation:

Let the number of pens and pencils that Alex has be represented by n and m respectively.

But,

number of pens, n = 14

number of pencils, m = 57

Then,

total number of pens and pencils, p = number of pens + number of pencils

i.e p = n + m

p = 14 + 57

p = 71

The total number of pens and pencils that Alex has is 71.
