Answer:
You would have $1,251 more money in second city bank than the first city bank.
Explanation:
First city bank pays 7% simple interest.
Interest = (PRT)/100
Interest = (6000 * 7 * 9)/100 = 378000/100 = $3,780
Amount in first city bank after 9 years = 6000 + 3780 = $9,780
The second city bank pays 7% interest compounded annually, so we would find the amount after 9 years.
P = $6,000
R = 7% = 7/100 = 0.07
T = 9
A = P(1 + R) ^ {t}\\
A = 6000(1 + 0.07)^ {9}\\
A = 6000(1.07)^{9}\\
A = 6000 * 1.838459212420\\
A = 11030.75527452\\
A = 11031
Amount after 9 years in second city bank = $11,031
Difference between first city bank and second city bank: 11031 - 9780 = 1251.
