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.
Answer is
geometric series
Answer:
-2
Step-by-step explanation:
7 +7= 14. 14 + -2 = 12
The answer to question 1 is B
the answer to question 2 is B
2.7 = 27/10
27/10 = x/12
cross multiply
10x = 324
divide both sides by 10
x = 32.4
