"A pair of shoes that costs $40 was marked up by 25%. What was the markup and what is now the selling price. Show your work."

Answers

Original cost of a pair of shoes = $40
Percentage by which the price of the pair of shoes is marked up = 25%
Then
Amount by which the price
of the pair of shoes is marked up = (25/100) * 40 dollars
                                                      = 40/4 dollars
                                                      = 10 dollars
So
The selling price of the shoe now = (40 + 10) dollars
                                                      = 50 dollars
So we can see from the above deduction that the price of the pair of shoes was marked up by $10 and the selling price of the pair of shoes is $50. I hope the procedure is clear enough for you to understand.

Is 3-6x=y proportional

Answers

Answer:

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

The equation of a proportional relation is of the form

y = kx,

where k is a number.

Here you have

3 - 6x = y,

which can be rewritten as

y = -6x + 3

Because of the +3, your equation is not for the form y = kx, and it is not a proportional relation.

Round to the nearest hundredth 0.7553

Answers

What is 0.7553 rounded to the nearest hundredth?

0.76
It is: 0.76
0.76
It is 0.76 rounded to the nearest hundredth

If we can't go past the hundreths digits, then out numbers look like 0.71, 0.72, 0.73...

So, our number lies between 0.75 and 0.76. We have to see which one is closer, i.e. we have to subtract the numbers:

Since 0.0047 is smaller than 0.0053, we deduce that 0.76 is closer to 0.7553, and thus it's a better approximation.

ANSWER MY QUESTION I WILL GIVE YOU A BRAINLIEST Mickey used these calculations to find how much he would spend on 7 cartons of eggs, if 12 cartons of eggs cost $22.20. Describe his error.

12 cartons(÷22.20) $22.22(÷22.20)

Unit price = $0.54 $0.54(7) = $3.78

Answers

You would do the opposite of what he stated. So you would do $22.20 divided by 12. Which would be $1.85. So a carton of eggs costs $1.85. You would then multiply $1.85 by 7 and get $12.95.
22.20/12=1.85
1.85•7=12.95

X+y=14
2x+3y=38
what is x and y

Answers

Using the systems of equations, make the equation equal to
-2x-2y=-28
2x+3y=38
---
y=10
x=4
♥ {x,y} = {4,10} (X=4,Y=10)
♥ To solve replace x and y
♥ so for the first equation it would be
♥ 4+10=14 and that's true
♥ and for the second you have
♥ 2*4+3*10=38 so once again true.
