Answer:
Number of year = 13 year and 6 month approx.
Step-by-step explanation:
Given:
Amount invested = $80,000
Rate of interest = 6% compounded continuously
Future value of investment = $175,600
Find:
Number of year
Computation:
Future value of investment = Amount invested[1 + Rate of interest]ⁿ
175,600 = 80,000[1+6%]ⁿ
175,600 = 80,000[1+0.06]ⁿ
175,600 = 80,000[1.06]ⁿ
Number of year = 13.492 year
Number of year = 13 year and 6 month approx.
Answer:
x=17/2 y=1/6
Step-by-step explanation:
-1(x+3y=9)
1(x-3y=8)
_________
-x-3y=-9
x-3y=8
________
-6y/6=-1/6 y=1/6
x+3(1/6)=9
x+ 1/2=9
- 1/2 - 1/2
x=17/2
