A marathon takes place each year. In 2020 there were 6500 runners. Does this predict that in 2023 there will be more than 7500 runners? { Prediction : For each of the next 3 years the number of runners will increase by 5% } Does this predict that in 2023 there will be more than 7500 runners?

yes

there would be 7525 runners

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r) n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years  

6500 x (1.05)^3 = 7525 runners

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
