\(x = 2y\)
\(x\) is 75% of \(z\) :: \(x = \frac{3}{4}z\)
\(z\) is 175% of \(w\) :: \(z = \frac{7}{4}w\)
\(x = \frac{3}{4}z = 2y\) :: \(z = \frac{8}{3}y\)
\(\frac{8}{3}y = \frac{7}{4}w\)
\(w = \frac{32}{21}y\)
Answer C
\(x\) is 75% of \(z\) :: \(x = \frac{3}{4}z\)
\(z\) is 175% of \(w\) :: \(z = \frac{7}{4}w\)
\(x = \frac{3}{4}z = 2y\) :: \(z = \frac{8}{3}y\)
\(\frac{8}{3}y = \frac{7}{4}w\)
\(w = \frac{32}{21}y\)
Answer C
