Answer:
39%
Step-by-step explanation:
Let's find the answer by using the following formula:
selling price=(paid price)+((paid price)*(percent markup)) which can be written as:
percent markup=((selling price)-(paid price))/(paid price)
percent markup=(27.80-20)/20
percent markup=0.39=39%
In conclusion, the percent markup is 39%.
Answer:
-7-√15
Step-by-step explanation:
First move the constant to the right hand side and change it's sign
x^2+14x=-34
Then add (14/2)^2 or 7^2 to both sides
x^2+14x+49=-34+49
Then factor the expression
(x+7)^2=-34+49
Then solve (x+7)^2=15
You should get:
x=-√15-7
or
x=√15-7
P=2L+2W
L=Length
W=Width
P=Perimeter=16
So you have:
16=2×5+2w
Multiply 2 and 5 and get:
16=10+2w
Subtract 10 from both sides and get:
6=2w
Divide by 2 and get:
3=W
The width is 3.
24 1/2. 0.5 is equal to 1/2
