Answer:
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced problems.
The Pet-agree company is buying the collars at $1.19. They then have to increase the price in order to make a profit. They decide to mark it up 356% of the cost they paid. In order to calculate the Selling Price we need to first convert the percent into a decimal. We can do this by moving the decimal point two digits to the left.
356.00% ⇔ 3.56
Now we can multiply the decimal by the original cost of the collar.
$1.19 × 3.56 = $4.236
Rounded up the Selling price of the collar would be $4.24. But the question asks us for the amount of the mark up, so we need to subtract the selling price from the buying price.
$1.19 - $4.24 = $3.05
The amount of mark-up from the original price is a $3.05 difference.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Answer:
x = -3 or x = 5
Step-by-step explanation:
Solve: x^2 -2x = 15
x^2 - 2x - 15 = 0
Use the Diamond method of factoring
-15 = 3* -5 and 3 - 5 = -2 so...
x^2 - 2x - 15 = x^2 - 5x + 3x - 15
x^2 - 2x - 15 = x *(x - 5) + 3*(x - 5)
x^2 - 2x - 15 = (x + 3)*(x - 5)
x^2 - 2x - 15 = (x + 3)*(x - 5) = 0
solve (x + 3 ) = 0 and (x - 5) = 0
x = -3 or x = 5
Answer:
AB = 4.73
Step-by-step explanation:
Given BC = 2 and A = 25
°
To find AB we have to use sin function in trig equation:
sin A = BC/AB
sin 25° = 2/AB
Multiply both sides by AB
AB x sin 25° = 2
AB x 0.42 = 2
Dividing the equation by 0.42
AB = 4.73
