$- 32.98$

#### Explanation:

$- 0.2 \times 22.4 - 28.5$
When you look at the equation, it is a little confusing. But if you take it step by step, it's fairly simple

By order of operations , we know that we have to multiply $- 0.2 \times 22.4$ together before we subtract anything. To make it easier, I'm going to put in parentheses.
$\left(- 0.2 \times 22.4\right) - 28.5$
$\left(- 4.48\right) - 28.5$

This simplified part looks a little confusing. How do you subtract from a negative number? Well, if I add a little "+" mark, it becomes a bit easier.
$- 4.48 + - 28.5$

This is exactly like adding now, all we have to do is keep the negative sign in the answer since they are both negative numbers.
$- 4.48 + - 28.5 = - 32.98$
