To calculate the total cost for Angela's purchase, we'll need to multiply the quantity of each item by its respective price and then sum up all the costs.
Let's calculate the cost for each item:
Cost of cups = 12 cups * $2.25 per cup = $27
Cost of plates = 6 plates * $5.75 per plate = $34.50
Cost of bowls = 6 bowls * $300 per bowl = $1,800
Now, let's calculate the total cost by summing up the costs of all the items:
Total cost = Cost of cups + Cost of plates + Cost of bowls
Total cost = $27 + $34.50 + $1,800
Total cost = $1,861.50
Therefore, the total cost for Angela's purchase of 12 cups, 6 plates, and 6 bowls is $1,861.50.
