Answer:
$120
Step-by-step explanation:
Let the initial value of bond be $X
The future value of any bond is calculated by formula
FV= PV(1+r)^n
where
- FV is future value of bond
- PV is present value of bond
- r is the rate that at which value of bond appreciate
- n is the number of years of maturity
In the problem given
FV= $146
r = 4% = 0.04 (dividing 4 by 100 we get 0.04)
n = 5
substituting these value in formula
PV =$X = $120
Hence current value of bond is $120.
1h 15minutes, I converted each time into fractions, 2hours to 
and the 8hour to 
, this means, painter #1 finishes 1/2 of the project in 1 hour, and paither #2 finishes 1/8 of project in 1 hour, now when we make each fraction out of 2 hours, so 
and 
, we add them and get 
, then as mixed number, 1 1/4 which is 1 hour and 15min<em>(1/4 of a hour)</em> I believe im right.
