Let the number of chemistry books be x and the number of calculus books be y
total number of books in each case is:
x+y=24
x=24-y.....i
Weight of each case:
2707.2/20
=135.36
thus
4.2x+6.0y=135.36..ii substituting i in ii
4.2(24-y)+6y=135.36
100.8-4.2y+6y=135.36
hence
1.8y=34.56
y=19.2
hence
x=24-19.2
x=4.8
thus the number of chemistry books was 4.8*20=96 number of calculus was
19.2*20
=384 books
Answer:
Kaden had $17 at first
Step-by-step explanation:
Ben = x
Kaden = x - 10
x + 4
x - 10 + 4 = x -6
x - 6 = 
x
9(x - 6) = 7x
9x - 54 = 7x
2x = 54
x = 27
x - 10 = 27 - 10 = 17
