Answer:
D) 1541
Step-by-step explanation:
I like to answer it w without deriving the formula of f(g(x)). So, we go this way, you firstly have to find g(7) which will be equal to 3 * 7 - 5 = 16.
And then you find f(16) = 6*16*16+5 = 1541. That's all.
1+3+6=10
40=10 units
diidde by 10
4=1unit
4 times 1=4
4 times 3=12
4 times 6=24
they paid $4, $12 and $24
