Let's assume Angela's weekly allowance is $x.
According to the problem, she spent half of her weekly allowance at the movies. Therefore, she spent (1/2)x dollars at the movies.
After going to the movies, Angela earned $5 by cleaning the windows. So, she has [(1/2)x + $5] left.
We are given that Angela ended the week with $8. So, we can write the equation:
[(1/2)x + $5] = $8
To solve for x, we can start by subtracting $5 from both sides of the equation:
(1/2)x = $8 - $5
(1/2)x = $3
Now, to isolate x, we multiply both sides of the equation by 2:
x = 2 * $3
x = $6
Therefore, Angela's weekly allowance is $6.
Angela earns a weekly allowance at the start of each week. She started the week with just her weekly allowance. Then she spent half of her weekly allowance at the movies to earn more money. Her parents let her clean the windows in the house for five dollars. what is her weekly allowance if she ended the week with eight dollars solve using arithmetic or algebra and explain your steps
