Answer:
t = 2 years and 6 months
Explanation:
I = Prt
in order to solve this :
make t the subject of formula
t = I/Pr
now input the values given
![t = (81)/(1200 * (2.7)/(100) )](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yxjrhc99b1nhjofzmlrvue8269g7fj4jul.png)
t = 2.5
this means 2.5 years , we can make this value exact :
2.5-2 = 0.5
0.5 * 12 months = 6 months
hence t = 2 years 6 months
