A scientist raised $32,506 for his project. He later found out that he would need $57,500 to completely pay for it. How much more money does the scientist have to raise? A. $24,994 B. $25,994 C. $89,006 D. $90,006
we need to subtract: the scientist needed 57,500 dollars, but already had 32,506, so we need to find what's left: 57,500 - 32,506 = 24,992 dollars
Your answer is A. Hope that helps! :)
