Answer:
The answer is C (the third one).
Step-by-step explanation:
Let represent the amount of weeks.
Sienna has $8, and she saves $3 per week.
In other words, after weeks, she will have dollars.
Similarly, Jacob has $6 and is saving $4 per week.
In other words, after weeks, he will have dollars.
Choice C is the only one that represents this scenario:
(For Sienna:) three (green) bars with eight equals
(For Jacob:) four (green) bars with six .
Choice C is correct.
