Find what each banana costs by dividing the $15 dollars between the 10 bananas 15/10=$1.5 then times by 3 to get how much 3 bananas cost $1.5*3= $4.50
This would be an increase. You would have one fraction with 46 over 24 and next to it you would have X over 100. Multiply 46 times 100 and then divide that number by 24. This would be an increase of approximately 191.6
