A music store marks up the instruments it sells by 40%. If the store bought a guitar for $35, what will be its store price? If t
Black_prince [1.1K]

Answer:

a. $49

b. $74.28

c. No

Step-by-step explanation:

The computation is shown below:

a. The store price is

= Purchase price + markup

= $35 + $35 × 40%

= $35 + $14

= $49

b. The price paid is

Since there is a markup of 40% and when it is added to 100% of cost so the selling price is 140% of the cost or 1.40 of the cost

Now the price paid is

$104 = 1.40 × cost

So, the cost is

= $104 ÷ 1.40

= $74.28

c. Now the markup is

= $100 - $75

= $25

The markup percentage is

= $25 ÷ $75

= 33.33%

No the store does not markup the price by 40%

babunello [35]

Answer:

  The probability of the first draw is 100%, because the bead will be either red or white.  For the second draw, a different color must be drawn.

  So, if draw 1 is white, then the probability of draw 2 being red is 7/10.  and if the first draw is red, then the probability of draw two being white is 5/10.

What are the coordinates of the vertex of y=x²+4x+3?​
Travka [436]

Answer:

(-2, -1).

Step-by-step explanation:

y = x² + 4x + 3

Completing the square:

y = (x + 4/2)^2 - (4/2)^2 + 3

y = (x + 2)^2 - 4 + 3

y = (x + 2)^2 - 1.

This is vertex form and the coordinates of the vertex are (-2, -1).
