Answer:

34 hours

Step-by-step explanation:

Lets call M the number of hours that Maddie volunteered. Ryan volunteered 1 + 3×M hours, and altogether they volunteered 45 hours, so:

1 + 3×M + M = 45

1 + 4M = 45 Subtract 1 in both sides

4M = 44 Divide both sides by 4

M = 11 hours

So Maddie volunteered 11 hours, and Ryan volunteered

1 + 3×11 = 34 hours

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%.
