Benny spent half of his allowance going to the movies he washed the family car and earned 8 dollars. What is his weekly allowance if he ended with 16 dollars
Let's start by setting up an equation to represent the given information:
Benny's allowance = x
Benny spent half of his allowance going to the movies = 0.5x
Benny earned 8 dollars washing the family car
So, we can write the equation:
x - 0.5x + 8 = 16
Simplifying the equation, we get:
0.5x = 8
x = 16
Therefore, Benny's weekly allowance is $16.
