Answer:
Let the original price be 'x'
7/100 * x + x = 305
(7x+100x)/100 = 305
107x = 305 * 100
107x= 30500
x= 30500/107
x= 285.04
Therefore, the original buying price is £ 285.04

Answer:
Third option
x ≠2 and x cannot be any value for which v(x) = 0
Step-by-step explanation:
In this problem we are asked to find the domain of the function

We know that
.
We know that:
Domain of U(x) is all real numbers except <em>x = 0</em>
Domain of V(x) is all real numbers except <em>x = 2</em>.
Then the domain of the composite function U(V (x)) is:
all real numbers except <em>x = 2</em>. (since <em>x = 2</em> does not belong to the domain of V(x) and all values of x for which <em>V(x) = 0</em> (since <em>x = 0</em> does not belong to the domain of U(x))
Finally the domain of
) is:
and 
You were right 24 is the answer. :)
