Deangelo · Answer 1

gf (p) = 0.5225p

Step-by-step explanation:

f (p) = 0.5p is the sale price.

g (s) = 1.045s is the amount to be paid.

1.045 (0.5p) = 0.5225p

Which is substituting 's' by '0.5p'

Or 's' by f (p) in g (s)

Which gives:

g (f (p)) = gf (p)

gf (p) = 0.5225p

Anabella · Answer 2

f (p) = 0.5p is the sale price.

g (s) = 1.045s is the amount to be paid.

1.045 (0.5p) = 0.5225p

➡️Which is substituting 's' by '0.5p'

Or 's' by f (p) in g (s)

Which gives:

g (f (p)) = gf (p)

gf (p) = 0.5225p
