What annual simple interest rate will increase jacob davidson’s initial investment of $5,000 to $6,000 in two years?
multiple choice
a)10%
b)5%
c)4%
d)6%

Hence, the annual simple interest rate is:

10%

The initial investment(I) of Jacob Davidson=$ 5000.

Time(T)=2 year.

Interest(I') earned by him=His income after investment-His initial investment.

                                    = $ (6000-5000)

                                    = $ 1000.

Now, the rate of interest(R) is given by :

Hence, the annual simple interest rate is:

10%

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
