Answer:
210 books
Step-by-step explanation:
Hello
I think I can help you with this
Step 1
if one box is 7.5% of the total shipment, how many box is the total shipment
1 box =7.5%
x?box=100%
using a rule of three
Now, isolating x
13.34 boxes is the total
Step 2
find the total of books
we will need 14 boxes, because it does not exist 0.34 box
so, the total of books=
number of boxes*number of books included in each box
=14 boxes*15 books
=210 books
Have a great day
