Answer:
oki! Mizuki is here to help!
The answer is 61 cars!
Step-by-step explanation:
<em>First, let's find how much money she needs to earn!</em>
105 + 500 = 605
<em>Then, we will divide the amount she needs to earn by the amount per each car!</em>
605 ÷ 10 = 60.5
<em>We get 60.5 As an answer but... since we must wash a whole car, we will round it up and get 61 cars as the answer!</em>
