Answer:
1. The school colors of Isabel are green and black.
2. Shane wants to make the color green by mixing blue paint with some other color.
3. It is not specified how many parts of blue and the other color are needed to achieve the correct shade of green.
4. The question asks how many parts of yellow paint are needed to make sixty-four parts of green paint.
Since the exact proportions for mixing blue and another color to make green are not provided, it is challenging to determine the precise answer. The question implies the existence of a specific ratio or recipe for creating green, which is missing from the information given. Without that information, it is not possible to calculate the amount of yellow paint needed to make sixty-four parts of green paint.
