Question 1123778: Mike spent half of his allowance going to the movies.he washed the family car and earned 7 dollars.what is his weekly allowance if he ended up with 17 dollars? Answer by ikleyn(52775) (Show Source):
Let x = Mike's weekly allowance, which is under the question.
Then is what was left after buying the movies tickets.
Plus to it Mike earned 7 dollars.
The condition says
+ 7 = 17.
Then = 17 - 7 = 10; hence, x = 2*10 = 20 dollars.
Answer. Mike's weekly allowance is 20 dollars.
