Bill roe visited his local bank to see how long it will take for $1,000 to amount to $1,900 at a simple interest rate of 12 1/2 percent. could you provide bill with the solution to his problem in years?

7.2 years.

Step-by-step explanation:

Bill Roe visited his local bank to see how long it will take for $1,000 to amount to $1,900 at a simple interest rate of %

Formula of simple interest

A = P(1+rt)

A = Future amount

P = principal amount

t = time

r = rate of interest

1,900 = 1,000(1 + 0.125t)

1,900 = 1,000 + 125t

125t = 1900 -1000

125t = 900

t = = 7.2 years

It will take 7.2 years.

yes. we do proportions in probabilities.
