The answer would be that she has an weekly allowance of 16$
Step-by-step explanation:
First you found out that she had 12$ at the end of the week so it said she washed her parents car for 4$ but that isnt part of her weekly allowance so you would subtract by 4 and get 8. Then it says she spent half of it on mini golf so you times it by two and get an allowance of 16$ :)
You have to multiply the previous year $ with 5.5% or 0.055 (they're the same) .The price would increase by 849.91500 so when you add the previous price with the 849.91500, you would get $16302.915
