Elsa’s friend borrows $400 with an interest rate of 1.5%. How much interest will she pay after 4 years?

Formula I = P x r x t

p is the principal amount, $400.00

r is the interest rate 1.5% a yea (0.015 in decimal)

t is time involved 4 years

so t is 4 year time periods

To find the simple interest we multiply 400 x 0.015 x 4 to get $24.00

so if you borrowed the $400 dollars you would now owe $424

so it's $24 interest or $424 since it's usually added to the principal

answer and step-by-step explanation:

400 =

1.5% = 0.015%

4years = 0.015%

(correct me if im wrong)

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
