Answer:
1.4 years
Step-by-step explanation:
Use the formula for simple Interest:
[tex]I = P * r * t[/tex]
Where I is the interest gained (in your case $105),
P is the principal (in your case $6000),
r is the annual interest rate in decimal form (in your case 0.0125)
and t is the time (in years) you need to find.
Therefore, we [tex]105 = 6000 * 0.0125 * t = 75 * t\\t = \frac{105}{75} = 1.4 years[/tex]solve for "t" in the following equation:
