Answer:

Irene's share = 29

Charlie's share = 18.5

Explanation:

R bill = 47.5

Irene's share = (2 × Charlie's share )-8

Irene's share = y

Charlie's share = x

bill = x + y = 47.5

y = 2x -8

x + 2x - 8 = 47.5

3x = 47.5 + 8= 55.5

x = 18.5

y = 29

Explanation:

let Irene's share be x and Charlie's share be y

x=2y-8

x+y=$47.50

x=$47.50-y

$47.50-y=2y-$8

$47.50+$8=2y+y

$55.50=3y

y=$55.50/3

y=$18.50

x=$47.50-$18.50

x=$29
