Answer 2

Answer:

See answer below

Step-by-step explanation:

Hi there,

Get started by developing a relationship between the amount of sugar for 1 cake. We can use dimensional analysis to solve this.

$\frac{9.9 \ g \ sugar}{1 \ cake}$

Now, we know that we need 8 cakes. We put 1 cake on the bottom of the fraction so that it cancels out with the 8 cakes unit:

$\frac{9.9 \ g \ sugar}{1 \ cake}$ $* \ 8 \ cake = 9.9 g \ sugar * 8 = 79.2 g \ sugar$
