Question

If James grows by 20 inches everyday starting

Monday, what is the difference in his height
between Wednesday and Monday?​

Answer 1

Okay so if James grows 20 inches everyday between Monday and Wednesday that is 3 days (Monday, Tuesday, Wednesday). When it asks for the difference it is asking for how many inches he grew in total. So let’s call the “difference” Y.
The equation would be...
3 x 20 = Y
60 = Y
Therefore, the answer would be 60 inches.
