1.3*3=3.90
3.90*35=136.50
136.50 is all you need to provide at least three of the most expensive items.
You still have 13.50 left over
Given:
Initial cost of living = $44,000
Rate of increase = 5% = 0.05
To find:
The cost of living in 20 years.
Solution:
The exponential growth model is:

Where, a is the initial value, r is the growth rate and t is the number of years.
Putting
in the above model, we get




Therefore, the cost of living in 20 years is about $116745.10.
Answer:
(8, -1)
General Formulas and Concepts:
<u>Algebra I</u>
- Reading a coordinate plane
- Coordinates (x, y)
- Solving systems of equations by graphing
Step-by-step explanation:
Where the 2 lines intersect is the solution to the systems of equations. The systems of equations intersect at (8, -1).
1) A
2)C
Constant is cost that can’t be changed so would be materials.
Coefficient is affected by something else, in this case, number of hours since cost per hour is 30.
Hope this helps!
