Answer: $225

Step-by-step explanation:

Each Notebook costs 45 dollars, this can be found by taking the cost of 2 (90$) and dividing it by 2

Now just take the cost per notebook (45) and multiply it by the amount wanted (5) and your total should come out to $225

Answer:

$225 = 5 note books.

45 = 1 note book

Step-by-step explanation:

90/2 = $45 EACH

Unitary method means find 1 part first.

Therefore,

1 part = 45

45 x 5 = 225

$225 = 5 note books.
