Strategy #2: Using 100 as an Anchor
The Spanish club is planning a weekend trip. Each student will need to pay $36 for transportation and $98 for food and lodging. What is the total cost per student?

  36
+ 98
------

To use 100 as an anchor,

1. Break down the addition:

   36 + 98 can be rewritten to find a way to make 100.

2. Break 36 into 34 + 2:

   34 + 2 + 98

3. Now add 34 + 98 to make 100:

   34 + 100 = 134

The total cost per student is $134.
