Sagot :
Answer:
Ana had $17 and Katie had $43.
Step-by-step explanation:
Since Ana and Katie together have $60, you can express this as follows:
x+y=60, where:
x is the amount that Ana has
y is the amount that Katie has
Also, Anna has $9 more than twice Katie's amount, which can be expressed as:
x=2y+9
The system is:
x+y=60 (1)
x=2y+9 (2)
Now, you can replace (2) in (1) and solve for y:
2y+9+y=60
3y=60-9
3y=51
y=51/3
y=17
Finally, you can replace the value of y in (2) to find x:
x=2(17)+9
y=34+9
y=43
According to this, the answer is that Ana had $17 and Katie had $43.
