In a school science project, students are tasked with creating a model of the solar system. They need to paint small spheres representing the planets. They have 12 spheres, each with a volume of 33.51 cubic inches. They plan to paint 75% of the spheres blue and the rest red. However, they accidentally painted 2 blue spheres red. How many blue spheres do they actually have now? Let's think step by step and output the final answer within \boxed{}.
