Parker has $40 and they purchase an instant camera for $55. The amount of money Parker has after the purchase can be calculated by subtracting the cost of the camera from their initial amount of money: $40 - $55 = -$15.
The correct answer is D. -15.
To determine the amount of money Parker has after the purchase, we need to subtract the cost of the instant camera from the initial amount of money Parker had.
Initial amount of money Parker had = $40
Cost of the instant camera = $55
Amount of money Parker has after the purchase = Initial amount of money - Cost of the instant camera
= $40 - $55
= -$15
Therefore, the number that represents the amount of money Parker has after the purchase is D. −15.
