Change = note - cost_of_apples

→ change = 10.00 - (3 x 0.65) = 10.00 - 1.95 = 8.05

Your question is written incorrectly. It should be: Each of these apples is ripe. The subject is Each (singular), so the verb must be singular, is. This is a singular sentence.

Sorry, but we are unable to help you since we are unable to view your drawing. Based on your question, I imagine the drawing is a square grid with some spaces that contain numbers and some that contain question marks. If you think about the problem and rephrase a specific question, we might be able to help you.

Assuming each question has the same number of marks, 1 question is worth 1.6666...% 100 divided by 60 = 1.66666666... However it is much more likely, especially if the test is in preperation for exams, that each question will be worth a different amount depending on the hardness of the question and how much detail/work needs to be put in to get the right answer, 1.66666...% is more an average of how much each question is worth, than how much each question is actually worth.

There's no reason they all have to be worth the same credit. Butif they are, then the number is 2.5% for each correct answer.
