School Store: Online Order Strategies

Use operation properties to calculate totals and check the order ledger.

Online Order Totals

Use operation properties to simplify calculations. In the store ledger, money received is positive and refunds or discounts are negative.

The school store receives 16 identical online orders. Each order contains the items below. Group the costs within one order before multiplying by 16.

Items in Each Order
Item	Quantity	Price each ($)
Folder	3	0.75
Pen	1	1.75

What is the total revenue from these orders? $

The store sells 48 supply bundles for $18.75 each. Which expression uses 48 = 50 − 2 to calculate the revenue correctly?

A. (18.75 × 50) − (18.75 × 2)
B. (18.75 − 2) × 50
C. (18.75 × 50) + (18.75 × 2)
D. (18.75 × 50) − 2

One order has no returned notebooks and one returned binder. Each return would change the ledger by −$6.80. Which statement correctly evaluates (−6.80 × 0) + (−6.80 × 1)?

A. The adjustment is $6.80 because multiplying by one reverses the refund's sign.
B. The adjustment is $0 because multiplying by zero makes the entire sum zero.
C. The adjustment is −$13.60 because both products equal the original refund.
D. The adjustment is −$6.80 because the products are zero and the original refund.
