Claudia Tanner · Answer 1

F (a) = 1.065a

g (b) = b + 20

g (f (a)) = g (1.065a) = 1.065a + 20

a is is the cost of furniture.

b is the cost of the furniture and sales tax.

f (a) is the cost of furniture and sales tax.

g (b) is the cost of the furniture, sales tax and delivery fee.

g (f (a)) is the cost of the furniture, sales tax and delivery fee.
