ariane borrows $400 on a 4-year loan. she is charged 5% simple interest per year . How much interest is she charged for 4 years?
vodomira [7]

Answer:

  1. Interests charged for 4 years: $80
  2. Total amount to pay back:$480

Step-by-step explanation:

  • To know the future value of an specific amount that is borrowed from a  bank we use the following equation: FV= PV\imes{(1+n\times{i})}, where FV is future value, PV present value, n the amount of periods and i the interest rate.
  • In this particular case, the present value of the loan is $400, n=4 (4 years), i=5%. Then the future value equals: FV= 400\times(1+4\times0.05). Then FV= $480, which is the total amount of money she would have to return in 4 years.
  • The interest paid can be calculated as the total amount paid ($480) minus the inicial loan ($400), which means that total interests paid= FV- PV= $80.

Answer:

\boxed{\sf 319:3388}

Step-by-step explanation:

Total number of tickets sold = 3388

Total number of coach tickets = 3069

Total number of first-class tickets = Total number of tickets sold - Total number of coach tickets

= 3388 - 3069

= 319

\therefore

Ratio of the number of first-class tickets to the total number of tickets = 319:3388
