If x is the price before a sale
x-0.15x=x-3
0.85x=x-3
3=0.15x
x=20
The original price is $20
The answer is A, due to that you multiply 12 times 6 and 12 times 2, which then you are adding and get the total answer.
The answer is A.
Add all the number values together and then divide it by the number of values you have: 43+32+65+88+50+72=350
350/6=58.33
It equals 18.32 you can go to calculatorsoup.com and it shows you
We equate the derivative of the function to 0 to find the x-value at its minimum:
f'(x) = 4x + 28
0 = 4x + 28
x = -7
Now, we put this value into the original equation to find the minimum value:
f(-7) = -106
The function has a positive slope so it will increase. Thus, the range will be y > -106
The answer is B
