Answer:
The correct answer is 60%.
Step-by-step explanation:
We know that the store had a profit of $ 30 for the pair of shoes sold.
Now we must transform that $ 30 into a percentage.
And one of the ways in which we can calculate this percentage is with the following percentage formula:
P is the percentage we want to calculate.
The number B is the profit we have obtained, 30
And number A is the total of the product, 50
Thus:
P= 60 %
Given this information, we can say that the percentage markup is 60%.
A difference is the result of a subtraction.
Call the number n.
"seven times a number": 7n
"eight more than four times the number": 4n + 8
"The difference between seven times a number and eight more than four times the number": 7n - (4n + 8)
Answer: 7n - (4n + 8)
Answer:
4x²+13x+9
iwill give you good method to simplify this
firstable take the 4 from x² and multiply it by 9
x²+13x+36
we find this equation
so the values is 4 and 9 because 4+9=13
4×9=36
(x+ )×(x+ )
first we take 9 and devide it by 4
9/4 the four for the x and the nine is number
so its will be
(4x+9)×(x+ )
same thing with 4 devide by 4 so the value is 1
so its will be like this
(4x+9)×(x+1) and this is the answer hopefully you understand my explain with my English
