Answer:

C. She did not follow order of operations.

Explanation:

Order of operations says you always have to multiply before you add when solving an equation, unless there are parentheses. Meaning that she should have multiplied -9 and 2/5 first before adding -18, instead of adding -9 and -18 first.
