Hi there
The formula is
A=p (1+rt)
We need to solve for t
T=[(A/p)-1]÷r
Where
A future value 2200
P present value 1000
R interest rate 0.08
T time?
So
T=((2,200÷1,000)−1)÷0.08
T=15 years

Answer:

Explanation:

Answer:

Reorder the terms:

8 + 6p + -4p = 3(p + 4)

Combine like terms: 6p + -4p = 2p

8 + 2p = 3(p + 4)

Reorder the terms:

8 + 2p = 3(4 + p)

8 + 2p = (4 * 3 + p * 3)

8 + 2p = (12 + 3p)

Solving

8 + 2p = 12 + 3p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-3p' to each side of the equation.

8 + 2p + -3p = 12 + 3p + -3p

Combine like terms: 2p + -3p = -1p

8 + -1p = 12 + 3p + -3p

Combine like terms: 3p + -3p = 0

8 + -1p = 12 + 0

8 + -1p = 12

Add '-8' to each side of the equation.

8 + -8 + -1p = 12 + -8

Combine like terms: 8 + -8 = 0

0 + -1p = 12 + -8

-1p = 12 + -8

The graph below shows the decline in the catch of groundfish (such as cod, haddock and flounder) from Georges Bank between 1965-
hoa [83]

Answer:

Approximately 22,000 metric tonnes of fish per year

Explanation:

From the graph,

Rate of decline :

(metric tonnes of fish in 1965 - metric tonnes of fish in 1995) / range of years

(700,000 - 40,000)metric tonnes ÷ (1995 - 1965)

660,000 metric tonnes ÷ 30 years

660,000 / 30

= 22,000 metric tonnes per year

Approximately 22,000 metric tonnes of fish per year
