Answer:

Brody purchased 16 songs.

Step-by-step explanation:

Ratio of the number of songs purchased by Brody(B) and Jayliah(J) = 2 : 3

\frac{B}{J}=\frac{2}{3} ------(1)

Similarly ratio of the songs purchased by Jayliah(J) and Sadie(S) = 4 : 5

\frac{J}{S}=\frac{4}{5} -------(2)

If Sadie bought the songs (S) = 30

From equation (2),

\frac{J}{30}=\frac{4}{5}

J = \frac{4\times 30}{5}

J = 24

By substituting the value J = 24 in equation (1),

\frac{B}{24}= \frac{2}{3}

B = \frac{2\times 24}{3}

B = 16

Therefore, number of songs purchased by Brody = 16.
