√324= √2^2•3^4= √2^2•√3^2•3^2= √2^2•√3^2•√3^2=2•3•3=18
1 / 7.15 = 1000 / x......$ 1 to 7.15 rand = $ 1000 to x rand
cross multiply because this is a proportion
(1)(x) = (7.15)(1000)
x = 7150 <=== Sophia got 7150 rand
If you were to compress a function vertically by a factor of n, f(x) would change to 1/n * f(x). Thus, choice C is the correct answer.
