Answer:
200 pencils and 120 pens
Step-by-step explanation:
Let the number of pencils be x while pens be y.
Considering the cost of whole purchase then, we get the equation
0.5x+y=220
Considering the number of items bought, then the equation is
x-y=80
Adding the two equations then we have
1.5x=300
x=300/1.5=200
Consideeing that x-y=80 and x is 200 then
200-y=80
y=200-80=120
Therefore, the pencils were 200 and pens 120 pieces
Answer:
6
Step-by-step explanation:
The trick here is to know PEMDAS.
PEMDAS stands for: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
This is the order in which you should simplify a problem.
Parentheses:
(5 + 1)^2 - (11 + 32) + 4
(6)^2 - (43) + 4
Exponents:
(6)^2 - (43) + 4
36 - 34 + 4
We have no multiplication or division, so we can skip those steps.
Addition:
36 - 34 + 4
40 - 34
Subtraction:
40 - 34
6
So 6 is our answer.
Answer:

Step-by-step explanation:
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
