Question

Kayla spent half of her weekly allowance on clothes. To earn more money her parents let her clean the oven for $4. What is her weekly allowance if she ended with $12?

Answer 1

In this question, the first information that we get is that Kayla spent half of her weekly allowance in clothes. On cleaning the oven Kayla gets $4. Finally Kayla is left with $12.
Let us assume that the weekly allowance of Kayla = x
Amount of allowance saved after buying clothes = x/2
 Then we can go for the equation
x/2 + 4 = 12
x + (4 * 2) = 12 * 2
x + 8 = 24
x = 24 -8
   = 16
So we can now see that the weekly allowance of Kayla is $16
