Answer:
The 16-oz bottle of parmesan cheese is the better buy.
Step-by-step explanation:
Even though 8-oz is half the amount of 16-oz, that doesn't mean it's cheaper. Let's find the amount of and 8-oz bottle when a 16-oz bottle is $5.78:
16-oz bottle of parmesan cheese = $5.78
A price of an 8-oz bottle when 16-oz is divided by 2:
16 ÷ 5.78 = $2.76
The original price of the 8-oz bottle should've been $2.76 but it's more expensive due to VAT.
So the 8-oz bottle is more expensive, therefore the 16-oz bottle is the better buy!
Answer:
The cost of 1 cupcake = $3.75.
Step-by-step explanation:
Let the cost of one cupcake = $ x.00
Now, the money spent by Cherie on 2 cupcakes = 2 ($x.00) = $2x
Also, the money spent by Sonya on 4 cupcakes = 4 ($x.00) = $4x
Now, according to the question:
$2x + $12.50 = $4x + $5.00
or, 2x + 12.50 = 4x + 5
⇒ 4x - 2x = 12.50 - 5
or, 2x = 7.50
or, x = 7.50/2 = 3.75
or, x = $3.75
Hence, the cost of 1 cupcake = $3.75.
