Problem of the Week: Film Frenzy

Aug 30, 2020

 

 

 

 

 

 

 

 

Did you figure it out?

 

Solution: Tyler already has 3 × 16 + 4 × 14 = 104 good pictures. To average 17 good pictures per roll, he needs 17 × 8 = 136 pictures to turn out in total. So, Tyler needs 136 – 104 = 32 photos on the 8th roll to turn out.

Look forward to next week's problem!
