Answer:
$16.
Step-by-step explanation:
Let x represent Benny's weekly allowance.
We have been given that Benny spent half of his allowance going to the movies. So money spent on movies would be @@MATH_TOKEN_0@@.
We are also told that he washed the family car and earned 8 dollars. So money after washing the car would be @@MATH_TOKEN_1@@.
Since Benny ended with 16 dollars, so we can equate @@MATH_TOKEN_2@@ to 16 to solve for x as:
@@MATH_TOKEN_3@@
@@MATH_TOKEN_4@@
@@MATH_TOKEN_5@@
@@MATH_TOKEN_6@@
@@MATH_TOKEN_7@@
Therefore, Benny's weekly allowance is $16.
