Short answer: You are answering why?
Why doesn't she want to go out? She doesn't want to go out because she's in a very bad mood. She knows that she won't be good company.
Remark
The sentence after the ; (semicolon) does not begin with any kind of connective word. If you put a noun in place of she, you would see that the last part after the semicolon is a complete sentence.
Answer:
Jake earned $1,440 in commission.
Explanation:
Jake's commission is 15% of the amount he sells. To find the amount Jake has made in commission, we need to multiply the amount he sold, 9,600, by 15 and then divide it by 100.
9,600.15/100
=
144,000/100
=
1,440
Therefore, last week, Jake earned a total of $1,440, which is 15% of 9,600.
