Answer 1

210 books

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

`(1\ box)/(7.5 ) =(x)/(100)`

Now, isolating x

`(1\ box*100)/(7.5 ) =x\\x=13.34\ boxes`

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
