Ethan’s cookie recipe uses 3 cups of sugar to make 21 cookies. Mia’s recipe uses 4 cups of sugar to make 24 cookies. Who's recipe has more sugar per cookie?

Answers

Alright, so ethan’s cookies would be 21 cookies per 3 cups of sugar. So you would do 21/3 to find you get 7 cookies per one cup of sugar

Then Mias cookies are 24 cookies per 4 cups of sugar. You would do 24/4 to get 6, so 6 cookies per cup of sugar.

Mia’s cookies make less cookies per cup of sugar, so they’d have more sugar in them.

Mia- 6:1

The selling price of an item is ​$390. It is marked down by ​10%, but this sale price is still marked up from the cost of ​$270. Find the markup from cost to sale price.

Answers

Answer:

find the actual discount, multiply the discount rate by the original amount 'x'. To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price. Solve the equation and find the original amount 'x'.

Step-by-step explanation:

Sale Price = $11.34 (answer). This means the cost of the item to you is $11.34. You will pay $11.34 for a item with original price of $12.60 when discounted 10%. In this example, if you buy an item at $12.60 with 10% discount, you will pay 12.60 - 1.26 = 11.34 dollars.

The markup from cost to sale price is 81 dollars.

What is the cost price?

Cost price, for instance, equals selling price plus profit ( when selling price and profit is given )

Cost is equal to Selling price plus Loss ( when selling price and loss is given )

The Cost price = 100 Selling Price + 100 + Profit

where the Selling Price and Profit Percentage are supplied.

The selling price of item = $390

cost = $270

10% × $390 = $39

Now subtract 39 from 390

390 - 39

351

Now subtract 270 from 351

351- 270

81

$81 is markup price .
