Answer:
effective interest rate: 2.37%
Step-by-step explanation:
250,000 x 1% = 2,500
We will calcualtethe interest expense for the credit line and the interest revneue for the credit being in short-term investment through the whole year
so we got:
Principal 250,000.00
time 4.00
rate 0.00175
Amount 267,964.76
interst expense for the credit line 17.964.76
2,500 will be deposited
if we keep the credit line available through short term investment we will got:
Principal 247,500.00
time 4.00
rate 0.01200
Amount 259,595.56
interest revenue 12.095,56
so we recieve 247,500
and paid 17.964.76 interest
and gain 12.095,56
interest net: 5.869,2
5,869.2/247,500 =0,02371393 = 2.37%
