Solution:
1. Initial amounts:
- Jeremiah:

USD 40

- Sonita:

USD 20

2. Weekly savings:
- Jeremiah:

USD 5

per week
- Sonita:

USD 10

per week

3. Let the number of weeks be

w

.

4. Amount after

w

weeks:
- Jeremiah:

40 + 5w

- Sonita:

20 + 10w

5. Set the amounts equal to find

w

:

40 + 5w = 20 + 10w

6. Solve for

w

:

40 + 5w - 5w = 20 + 10w - 5w

40 = 20 + 5w

40 - 20 = 5w

20 = 5w

w = \frac{20}{5} = 4

7. Therefore, they need to save for

4

weeks before they have the same amount of money.

Answer:

w = 4

User One of the applications of the derivative of a function is its use in Physics, where a function that at every instant t associates the number s(t), this function s is called the clockwise function of the movement. By deriving the time function we obtain the velocity function at time t, denoted by v(t). A body has a time function that determines its position in meters at time t as S(t)=t.³√t+2.t . Present the speed of this body at time t = 8 s.
