283.3%
Step-by-step explanation:
6.8 divided by 2.4 = 2.83333333333
2.8333 x 100 = 283.33

After x weeks:
Jules will have: 1,200 + 40 x.
Kelsey will have: 400 + 50 x.
If we want to know in how many weeks will they have the same amount of money, we will make an equation:
400 + 50 x = 1,200 + 40 x
50 x - 40 x = 1,200 - 400
10 x = 800
x = 800 : 10
x = 80
Answer: In 80 weeks they will have the same amount of money.

Step-by-step explanation:
An arithmetic sequence has a common difference between adjacent terms. Here, the differences are ...
The differences are different, not common, so this is NOT an arithmetic sequence.
You can isolate r to one side of the equation by dividing by adding three, dividing by s, multiplying by a and you get:
r=a(3+k)/s
