Answer:
100 - 75 = 25%
25%=119.60
need to find 1%
25/25=1%
119.60/25=1%
1%=4.784
now multiply by 100 to find original price
100% = 478.40
original price £478.40
Well, 1/2 is equal to 5/10... so 7/10 - 5/10 is 2/10 because 7-5=2 :)
The function can use all values of x which means x is in between -inf and +inf. The first option expresses this.
Y ^(-2/3)^-6 = y^12/3 = y^4
x^(1/2)^ -6 = x^-3 = 1 x^3
so the answer is y^4 * 1 /x^3 = y^4 / x^3
