How much did Benny add in January and February? ** In January and February, Benny added 19 + 19 = $<<19+19=38>>38 to the piggy bank.
How much did Benny save in March? ** Calculating the difference between this and the total he has at the end of March shows that he saved 46 – 38 = $<<46-38=8>>8 in March.
