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

[tex]\frac{1\ box}{7.5 } =\frac{x}{100}[/tex]

Now, isolating x

[tex]\frac{1\ box*100}{7.5 } =x\\x=13.34\ boxes[/tex]

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
