Answer:
$5
Step-by-step explanation:
This one is very simple and we use an algebraic expression to find how much money Sinda has left.
Let m = her money remaining
[tex]45 - (11+29) = m[/tex]
From here we have to complete what's in the parentheses: [tex]45 - 40 = m[/tex]
And now we do simple subtraction to find m: [tex]5 = m[/tex]
(Your teachers may want you to keep the variable on the left side so switch 5 and m if needed)
Therefore, Sinda has $5 left.
