Tracy took 12 pictures during 4 days of vacation. How many days will it take for Tracy to take 21 pictures ?

Sounds like Tracy is averaging three photos a day so she would take 21 in seven days

p=pictures
d=days of vacation
12p=4d
divide both sides by 4 to get
3p=d
3pictures every day
21p=_d, 21/3=7
7 days!
