Answer:
- a. $2480
- b. $4040
- c. 4 years and 2 months
- d. 8 years and 4 months
Step-by-step explanation:
a. Account after 4 years:
- 2000 + 4*2000*0.06 = $2480
b. Account after 17 years:
- 2000 + 17*2000*0.06 = $4040
c. Time when account = $2500:
- 2000 + x*2000*0.06 = 2500
- 120x = 500
- x = 500/120
- x = 4 20/120 = 4 2/12 years = 4 years and 2 months
d. Time when account = $3000
- 2000 + x*2000*0.06 = 3000
- 120x = 1000
- x = 1000/120
- x = 8 40/120 = 8 4/12 years = 8 years and 4 months
