Answer
Let the length of the holiday be x days.
At the end of the holiday Adam had 155 + 32x
At the end of the holiday Kayla had 35 + 52x
35 + 52x = 155 + 32x
52x = 120 + 32x
20x = 120
x = 6
The holiday lasted six days.

Teacher, do your students have one to one
access to computers? Whether your students each have a TabletPC or share a desktop PC, this activity lends itself to eLearning (Engaged Learning). |
