Wrong answer in test set

Question: The girls are trying to raise money for a carnival. Kim raises $320 more than Alexandra, who raises $430, and Maryam raises $400 more than Sarah, who raises $300. How much money, in dollars, did they all raise in total?
Given answer: 2280
Correct answer: 2180
Answer from OPUS4.6:
Let me work through this:
Alexandra raises $430. Kim raises $320 more than Alexandra, so $430 + $320 = $750. Sarah raises $300. Maryam raises $400 more than Sarah, so $300 + $400 = $700.
Total: $430 + $750 + $300 + $700 = $2,180.
This question is also wrong:
"Marin and his neighbor Nancy each eat 4 apples a day. How many apples do they eat in 30 days?"
Here's the dataset's answer :
"In one day, Marin and Nancy eat 4 + 1 = <<4+1=5>>5 apples.
In 30 days, they eat 30 * 5 = <<30*5=150>>150 apples.
#### 150"
Where does the "+1" come from ? The valid reasoning should be 4230 here, as there is no indication whatsoever to add an apple to make it 5.
