Answer:

Step-by-step explanation:

a) -x-4(1-x) =

− 2 x −4 ( 1 − x ) .

2 x − 4

b) 3(5x-2)-5(3-4x) =

3 ⋅ (5 x − 2 ) − 5 ⋅ ( 5 − 4 x )

35 x − 31

c) √2(3-x)-2(1-x√2) =

√ 2 x ⋅ ( 3 −x ) − 2 ⋅( 1 − x √ 2 ) .

2 x √ 2 + 3 √ 2 x -√ 2 x x − 2

In calculating the present value of $1,000 to be received 5 years from today, the discount factor has been calculated to be .700

Trava [24]

To calculate the present value we shall proceed as follows:
from the present value table, the percentage corresponding to discount factor of 0.7008 in 5 years is 7%
therefore using the formula:
FV=PV(1+r/100)^n
where:
FV=$1000
PV=?
r=7%

hence:
1000=PV(1+7/100)^5
PV=1000/(1+7/100)^5
PV=712.986
