1 answer:
<u>Answer:</u>
The original selling price is $520.632
<u>Explanation:</u><u> </u>
Consider the initial selling price be $x
After marking down 10%,
Final Selling price = Selling price(1-10%)
Selling price = x – 10% of x = x – 0.1x = 0.9x
After marking 30%
Final Selling price = Selling price(1-10%)
Selling price = 0.9x – 0.3*0.9x = 0.9x – 0.27x = 0.63x
According to the question,
0.63x = 328
Therefore, the original selling price is $520.632

Answer: y =
Step-by-step explanation: look for the lcm
a=
cross multiply
ax =9xy + 2
ax - 2 = 9xy
divide both sides by 9x
y=
The quadratic formula is
A = 2
B = -30
C = 108
plug in the values for the equation and you'll get what the factors are
-(-30)+√(-30)²-4(2)(108))/2(2)
and
-(-30)-√(-30)²-4(2)(108))/2(2)
This will give you your A values
and just round the answers from both of the above equations
