Question

A new movie opened in a local theater. On opening day, 985 people saw the movie. Each day after opening day, the number of people seeing the moving dropped by roughly 20%. Approximately how many people saw the movie in that theater in the first 7 days?

Answer 1

About 3891 people saw that movie.

Explanation:

Day 1: 985 people

Day 2: (985*8)/10 (20% gone) = 788

Day 3: (788*8)/10 (20% gone) = 630.4

Day 4: (630.4*8)/10 (20% gone) = 504.32

Day 5: (504.32*8)/10 (20% gone) = 403.456

Day 6: (403.456*8)/10 (20% gone) = 322.7648

Day 7: (322.7648*8)/10 (20% gone) = 258.21184

Adding this up:

985+788+630.4+504.32+403.456+322.7648+258.21184=

985+788+630+504+403+323+258=3891
