This is a case of exponential growth. The appropriate equation, with the given data inserted, is P(t) = 500 ( 1+0.15)^50
or = 500 (1.15)^50
Evaluate this on your calculator.
Answer:
g=2
f=5
Step-by-step explanation:
- add g to the other side on the 2nd equation. you should get f=7+g
- now replace the f in the top equation with 7+g. the equation should now look like 7+g +3g = 15
- combine like terms to get 7+4g=15
- subtract 7 from both sides to get 4g=8
- divide by four to get g=2
- now plug 2 in for g in the 2nd equation to get f-2=7
- add 2 to both sides and get f=5
