Hello from MrBillDoesMath!

Answer:

10 - 3 sqrt(2)

Discussion:

Let f(x) =  6 + sqrt(14 + x) - sqrt(9x).  

Then

f(2) =  6 + sqrt(14 + 2) - sqrt(9*2)

      = 6 + sqrt(16) - sqrt(9*2)                 => sqrt(16) = 4

      = 6 + 4 - sqrt(9)*sqrt(2)                   => sqrt(9) = 3

      = 10 - 3 sqrt(2)

which is the first choice.

Thank you,

MrB

Gnoma [55]
That means that the discounts are the same
therfor 25% of original=180
multiply both sides by 4 or divide both sides by 0.25
original=720




the equation is
0.25 times original=180


and the original price is $720
