A. For each dollar the price increases, demand decreases by 450 units.
awnser 4x^2 + 20xy + 25y^2
X= purchase price
Multiply purchase price by sales tax % to equal the amount of sales tax.
(8.75% * x)= $15.75
convert % to decimal (8.75% ÷ 100)
0.0875x= 15.75
divide both sides by 0.0875
x= $180.00 purchase price
ANSWER: The purchase price is $180.00 (to nearest cent).
Hope this helps! :)
The way that it is written is odd.
If the problem was 3(x-5)=30, it would be 3x-15=30.
Add 15 to both sides.
3x=45
Divide both sides by 3.
x=15
If it's supposed to be 3(x-5)<30, your answer would be the same, except:
x<15.
I'm not sure why it has both signs, especially next to each other.
I hope this helps :)
