The subtraction operation

Step-by-step explanation:

Danielle was gifted $100 for her birthday which she planned buying a gown from. Now she bought some CDs totaling an amount of $47

The gown costs $43. Now, for her to be sure she has enough money to purchase the gown , the operation she needs to do is to subtract the money spent on CDs from the total money she had received.

And that is given by $100 - $47

This operation will give her the assurance that she indeed has enough money to purchase the gown after spending money on the CDs
