Answer:
25.2
Step-by-step explanation:
A calculator will evaluate this for you. If you don't have one, you can use a Google search box.

2(7 +2(2.8))
= 2(7 +5.6)
= 2(12.6)
= 25.2
Divide 1414 by 55 and you get 25.7 but you can't take .7 collections so the correct answer is 25 collections of 55 books
