Answer:
In approximately 70 weeks, Rena and Billy will both have about $155 saved, and Rena's savings will be greater than Billy's after that.
Explanation:
the first number 69.8 is on the x axis (weeks) and the second one 154.65 is on the y axis (savings)
after that point, you can see the red curve (rena's) goes by higher values of the y axis (savings) than the blue line.
