14) If $230 is invested for one year at 13.913.9% simple interest, how much interest is earned?

ratio = 42 in/22 yd

22 yd = 792 inch

ratio = (42/792) in = (7/132) in

B.

Principle = $230

rate = 13.9%

time = 1 yr

Interest = Principle*rate*time

Interest = 230*13.9*1/100 = $31.97

Interest = $31.97
