Answer: To solve this problem, we need to calculate the interest earned by Golda on her loan to Tida and subtract the interest paid to Yovvne.
First, let's calculate the interest paid by Golda to Yovvne on the loan of 4500 at a rate of 10% per year for 4 years:
Interest paid by Golda to Yovvne = Principal x Rate x Time
= 4500 x 0.10 x 4
= 1800
So Golda paid 1800 in interest to Yovvne over 4 years.
Next, let's calculate the interest earned by Golda on her loan to Tida of 4500 at a rate of 11.5% per year for 4 years:
Interest earned by Golda from Tida = Principal x Rate x Time
= 4500 x 0.115 x 4
= 2070
So Golda earned 2070 in interest from Tida over 4 years.
Therefore, Golda's net gain after 4 years is:
Net gain = Interest earned from Tida - Interest paid to Yovvne
= 2070 - 1800
= 270
Golda's net gain after 4 years is 270.
