Answer:
B) x - $16.50
Step-by-step explanation:
The problem is asking you to create an algebraic expression, so when you are talking about spending, paying or giving, that is usually a withdrawal from the main account, when you know that number you use the number, since we don´t know the actual amount we will use "x" to express that so we will withdraw from "X" the amount spent:
x-16.50
And that would be the expression of how much was left.
