i)
26/100 x 4.5
=1.17
(the discount price)
ii)
$4.5-$1.17
=$3.33
B=3d and b=d+4

First write (f o f)(x). This calls for us to use f(x) = 3x-2 as the input to f(x).
f(x) = 3x - 2 => f( ) = 3( ) - 2 Now subst. f(x) inside both sets of parentheses:
f(f(x)) (f o g)(x) = 3(3x-2) -2 = 9x - 6 - 2 = 9x - 8 (answer)
