Sandy spent half of her allowance going to the movies. she washed the family car and earned 9 dollars. what is her weekly allowance if she ended with 14 dollars ?

So if she had 14 dollars in the end, and 9 of those were from washing the car, we can subtract 9 from 14 to find how much money she had before she washed the car.

14 - 9 = 5

So if she had 5 dollars left after seeing the movie, and 5 dollars is the other half that she didn’t spend at the movie, then we can multiply 5 by 2 to get our answer

5 x 2 = 10

The answer would be Sandy’s weekly allowance is $10

I hope this helps! Please thank, rate, and mark as brainliest if my answer was the most helpful! <3

10 dollars because half of the allowance is 5 then she washed the car for 9 dollars ended up with 14 

It’s going to be d. 4x^2-4x-19’
