There are 40 students in a class. Each girl is given 5 books and each boy is given 4 books. The girls have 65 more books than the boys. How many more girls than boys are there in the class?

Hi Guest!

 

number of girls = g

number of boys = 40 - g

 

5g = 4(40 - g) + 65

Try solving for the number of girls yourself.  :)))

 

Here's the answer if you still needed it: 

 

5g = 160 - 4g + 65

9g = 225

g = 25

 

So the number of girls is 25, meaning the number of boys is 15 (40-25)

Our final answer is 10 (25-15)

 

I hope this helped. :))
