Answer:
Ann = 34 while betty has 17
Explanation:
let betty be y
let Ann be 2y, having $9 extra,
Ann will be 2y + $9
Ann and betty = $60
2y + $9 + y = $60
2y + y = $60 - $9
3y = $51
y = 51/3
y= 17
since Ann is 2y+9 and Betty is y
Ann = 2(17) + 9 while betty is 17
Ann = 34+9 and betty = 17
Ann = 43 and betty = 17
