A math teacher had $100 to buy three different types of calculators. A basic calculator costs $8. A scientific calculator costs twice the price as the basic while a graphing calculator costs thrice the price as the scientific. How much change did she receive after buying those three different types of calculators? Let's think step by step and output the final answer after "####".

A scientific calculator costs $8 x 2 = $<<8*2=16>>16.
A graphing calculator costs $16 x 3 = $<<16*3=48>>48.
So, she spent $8 + $16 + $48 = $<<8+16+48=72>>72 for the three calculators.
Therefore, the math teacher received $100 - $72 = $<<100-72=28>>28 change.
