To solve this problem, we simply need to identify the variables, where sunflowers are "s" and other flowers can be "f". Since we know that there are 8 rows of "f" for every 2 rows of "s", we can find that s=4f. This can lead to the equation:
2s+8f=240; or, when substituted, 2(4f)+8f=240.
We can solve this equation as 16f=240, or f=15.
Now, we can put f into s=4f, and find that s=60. So we can subtract the total number of rows by 60 to find the total number of "f" rows.
240-60=180.
This means that there are 180 rows that are NOT sunflowers.
Hope this helps!

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>
