Answer:
A) Total weekly salary = $1000 + ( 0.05 × s )
B) Yes this is a function
C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.
D) Domain will be [ 0, ∞ ]
Step-by-step explanation:

Weekly salary = $1000
Commission = 5% of all her sales
Let the number of sales be 's'
thus,
A) Total weekly salary = $1000 + ( 0.05 × s )
B) Yes this is a function
C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.

Hence,
sales will always be positive
thus,
domain will be [ 0, ∞ ]

Answer:During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942
Step-by-step explanation:
During the 10 year period,
Let x= increase in the number of
people living in Sherbury
y=number of people living in Sherbury before the increase
Therefore,
5/100 * y = x
0.05y=x
And
x + y = 20265
But y=20x
x + 20x =20265
21x=20265
x=965
During 10years ago the number of people living in Sherbury increased by 965.
Likewise
Let
a=increase in the number of
people living in Yaston
b=number of people living in Yaston before the increase
7.5/100 * b = a
0.075b = a
b=13.33a
a + b = 13502
a + 13.33a=13502
14.33a=13502
a=942
During 10years ago the number of people living in Yaston increased by 942.
Conclusion
During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942.
