Hi there!
This is very simple, so here's how to complete this math problem.
It looks like you're taking money away, so...
If you have 10$ and you spent 2 of them, the word 'spent' is a subtraction word, so we would subtract.
10$ - 2$ = 8$
So, therefore, you would still have 8 dollars left. :)
Hope this helps! :D
