A 90-day simple interest loan in the amount of $2,350 will be paid in full in the amount of $2,500.
puteri [66]

Answer:

  26%

Step-by-step explanation:

The amount due is ...

  A = P(1 +rt)

  2500 = 2350(1 +r(90/360)) . . . . using ordinary interest

  2500/2350 -1 = r/4

  r = 12/47 ≈ 25.53% ≈ 26%

The rate of the loan is about 26%.
