(C) 40-3X-5.75 0
(D) -3x+34.25 31.253​

Answer 1

40 - x - x - x - 5.75 OR 40 - 3x - 5.75 OR 34.25 - 3x

Explanation:

To find the amount of money Tim has left, we will simply write an expression that starts with the total he started with subtracting each expense.

$40

- $x

- $x

- $x

- $5.75

________________________

$40 - $x - $x - $x - $5.75

= $ (40 - 5.75) - 3(x)

= $ 34.25 - 3x

So you can choose one of three of these expressions:

(1) 40 - x - x - x - 5.75

(2) 40 - 3x - 5.75

(3) 34.25 - 3x

Cheers.
