Answer:

70

Step-by-step explanation:

Let the cost of each book be b and the cost of each bag be c. We're given

5b + 5c = 175

We can factor this as:

5(b + c) = 175

Divide each side of the equation by 5, we get:

(b + c) = 35

The problem asks for 2b + 2c

Factor out 2:

2(b + c)

we know from above that (b + c) = 35, so we substitute:

2(35) which would be 70.    :)
