Evageline does not have envy money but wants to purchase a scooter for $75. Represent how the cost of the scooter will affect Evageline’s total money as a number by completing the following equation

Total money = initial money - cost of scooter

So the equation can be represented as:
Total money = Evageline's initial money - $75

Let's represent Evangeline's total money as "M" and the cost of the scooter as "$75". Since Evangeline does not have enough money to purchase the scooter, we can represent this situation as an equation:

M - $75 = 0

This equation shows that if Evangeline subtracts the cost of the scooter ($75) from her total money (M), the result will be zero, indicating she will have no money left after the purchase.
