If you spend all $10 on peanuts, you could buy 40 bags of peanuts (20 x $0.50). However, if you want to get some popcorn as well, you need to subtract the cost of the peanuts from the total budget to determine how much money you have left for popcorn: $10 - (20 x $0.25) = $5. 
Since popcorn costs $0.50 per box, you can buy a maximum of 10 boxes of popcorn with the remaining $5 ($5 ÷ $0.50 = 10). Therefore, the best choice is B) 10.
