natka813 [3]

The price charged for the batch of cookies is $8.925

Step-by-step explanation:

Marked price refers to the price at which an establishment offers to sale a product. For-profits to occur, marked price is always more than cost price (cost of producing the item)

Here the local bakery has marked up the price by 155%. This means that the local bakery has increased the marked price by 155% above the cost price accrued to them.

The cost price of the cookies= $ 3.5

Hence the increased marked price= (155/100) *3.5

Increased marked price= $ 5.425

Hence the charge customers need to pay for the cookies= increased marked price + cost price

Charge = $5.425+ $3.5= $8.925

the price charged for the batch of cookies is $8.925

Solve this by substitution
frozen [14]

Answer:

y= 1 and x=-2

Step-by-step explanation:

Since they both equal y, you can equal them to each other:

x + 3 = 2x + 5

Then solve:

x - x + 3 = 2x - x + 5

3 - 5 = x + 5 - 5

-2 = x

Substitute x in either equation to solve for y:

y = (-2) +3

y = 1

Or the other equation:

y = 2(-2) + 5

y = -4 + 5

y = 1

hope this helps :)

THIS IS FOR MY TEST PLEASE HELP
AVprozaik [17]
2(3x+4y) = 2(24)
6x+8y = 48
Add both the equations
6x + 8y = 48
+ x - 8y = -20
—————————
7x = 28
x = 28/7
x = 4

Plug in this value in the second equation

(4) - 8y = -20
-8y = -24
y = -24/-8
y = 3

Therefore:
x = 4
y = 3
