Answer:
$739.2
Explanation:
we know that she earns $17.60 an hour. so if we add her regular 30 hours total to her added 12 hours total we will get her total pay. But first we need to multiply 17.60×30=$528, then we need to multiply 17.60×12=$211.2. Now we add them both up to receive her final total (528+211.2)=$739.2
I hope this helps!
