Answer:
$3, 774
Step-by-step explanation:
102 ice cream cakes, and 68 fruits tarts
One cream cake is $27 and a fruit tart is $15
Meaning, from ice cream cakes, they made 102($27) = $2754
From fruits tarts, they made 68($15) = $1020
given,
f(x)=(1/2)x-3
g(x)=2x+6
Now,
f(4)=(1/2)×4-3
=2-3=-1
g(4)=2×4+6=14
Then,
f(g(4))=f(14)=(1/2)×14-3=7-3=4
g(f(4))=g(-1)=2×(-1)+6=-2+6=4
