Mikaela earns $10 an hour tutoring. For the first month, she tutored for 35 hours and in the second month, she tutored 5 hours more than the first month. She spent 4/5 of her total earnings on her personal needs and saved the rest of the money. How much did she save? Give me reasons, before answering the question

Mikaela spent 35 + 5 = 40 hours in the second month. So, she tutored a total of 35 + 40 = 75 hours for the first two months. Thus, her total earning was 75 x $10 = $750. And, her total expenses was 4 / 5 x $750 = $600. Therefore, she saved an amount of $750 - $600 = $150. So the final answer is 150.
