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?
+2407 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. :))
