There are 14 male cousins and 10 female cousins.
Step-by-step explanation:
Let,
m be the male cousins and f be the female cousins
According to given statement;
m+f =24 Eqn 1
m= 2f - 6 Eqn 2
Putting value of m in Eqn 1
Dividing both sides by 3
Putting f=10 in Eqn 1
There are 14 male cousins and 10 female cousins.

Answer:
A: initial value: $750; rare of change: $60
B: y = 60t + 750
Step-by-step explanation:
Initial value = value when he started ( in 2000) =$ 750
Each year he add a constants to that value
'y' will be the amount he get after t years a amount increase each year
y = 750 + at
In 2010 his free = 1350
t = 2010 - 2000 = 10 year
y = 1350
y = 750 + at
1350 = 750 + 10 a
600 = 10a
a = 60
y = 750 + 60t ( his fee as a function of time)
In slope form: y = 60t + 750
He increases he fee by $60 a year.
