A radio station plays a total of 272 pop, rock, and hip-hop songs during a day. The number of pop songs is 3 times the number of

Norma-Jean [14]

Let the daily played number of pop songs be P, the number of rock songs be R and the number of hip-hop songs be H.

i)
"A radio station plays a total of 272 pop, rock, and hip-hop songs during a day"

means that : P+R+H=272

ii)
"The number of pop songs is 3 times the number of rock songs. "

so, P=3R

iii)
"The number of hip-hop songs is 32 more than the number of rock songs."

means: H=32+R

iv)

since both P and H can be written in terms of R, we have:

P+R+H=272

(3R)+R+(32+R)=272

3R+R+32+R=272

5R+32=272

5R=272-32=240

R=240/5=48

vi)

thus: P=3R=3*48=144, H=32+R= 32+48=80

Answer:

48 Rock, 144 Pop and 80 Hip-hop
