Question

Marcella has 6 fewer male cousins than female cousins. Let f represent the number of female cousins. Write an expression for the number of boy cousins.

Answer 1

Let the female cousins of Marcella be = f

Let the male cousins of Marcella be = m

As given, Marcella has 6 fewer male cousins than female cousins, so expression becomes

`m=f-6`

Answer 2

Let's assume

number of boy cousins =b

f represent the number of female cousins

and we are given

Marcella has 6 fewer male cousins than female cousins

so,

number of boys cousins = number of female cousins -6

so, we can replace it's variable

and we get

`b=f-6`...........Answer
