Answer:

Time of Day          Adult  Senior             Adult%  Senior%  

Afternoon                12         48                   20%       80%

Evening                  45          15                   75%       25%

Amelia predicts that when 400 tickets are sold on a Friday afternoon,  it can be expected that 80 of the tickets sold will be adult tickets.

  • Amelia is correct. If 400 tickets are sold in a Friday afternoon, you can expect 20% of them to be sold to adults = 400 tickets x 20% = 80 tickets sold to adults.

Stefan predicts that when 400 tickets are sold on a Friday evening,  it can be expected that 100 of the tickets sold will be senior tickets.

  • Stefan is correct. If 400 tickets are sold in a Friday evening, you can expect 25% of them to be sold to seniors = 400 tickets x 25% = 100 tickets sold to seniors.
