I'm assuming it's Simple Interest, as 5.8 is the answer obtained by the teacher.

Thus, this would be the second solution:

I= 6238 - 6000

= 238.

238= 6000 x 0.08 x T / 100 This should be 6000 x 7 x T /100

238= 480 x T / 100

T=238 x 100 / 6000 x 7 Correct!

= 56.7 No. 0.566...

= 57

Therefore, the money was invested for 57 days.

Am I right?

Thanks again.
