To evaluate the cost per juice box, we must first factor out the bag of apples from the equation. So we will disregard the price of the apples from the total price and also disregard the existence of the apples altogether.
Our new subtotal is $15.66 for eighteen juiceboxes. To find the cost for one juicebox, we divide the price & the # of juiceboxes by 18.
15.66÷18=0.87, therefore each juicebox is 87 cents.
Since a function would mean that a customer is able to purchase 1.1 of an item or 1.5 of an item, which is false. It also means that the customers pay the same price for a different amount of items.
