Using the calculator it is 27.47 round off to 27.5
Equation is f(x)=12,000(1.03)^13
the answer would be $17,622
if you were to plug into a scientific calculator

Step-by-step explanation:
- Masses of the bodies are x and y
- Distance at which they are kept is r
- When two bodies are of masses x and y are placed at a distance r then the gravitational force acting on them is given as:

- Where G is the gravitational constant.
The answer should be y=3x-3 hope this helps!
