Hi,

Let d be the days the 8 books were over due. Then (d+14) will be for the science books

8*.20d + 2*.20(d+14) = $11.60

simplify and Solve

1.60d + .4d + 5.60 = $11.60

2d = 6.00

d = 3 

3 days for the children's books

17 days for the science books



check your answer

8*.20*3 + .4*17 = 4.80 + 6.80 = $11.60
