How much time did Tony have between the end of the project and the beginning of band practice?

The correct answer is 43 minutes.

Step-by-step explanation:

Tony started his math project at 1:57 p.m.

Time taken by Tony to complete his project is 80 minutes = 1 hour 20 minutes.

Therefore Tony completed his project by 1:57 p.m. + 1 hour 20 minutes = 3:17 p.m.

Tony had his band practice from 4:00 p.m.

Thus Tony had 4:00 p.m. - 3:17 p.m. = 43 minutes between the end of the project and the beginning of band practice.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i
