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

Answer:

  • Ann: $43
  • Betty: $17

Explanation:

Let b represent the amount Betty has. Then Ann has 2b+9 and together, they have ...

b + (2b+9) = 60

3b = 51 . . . . . . . . . subtract 9

b = 17 . . . . . . . . . . divide by 3

Betty has $17 and Ann has the other $43 of the total of $60.
