Imani spent half of her weekly allowance playing golf. her parents gave her 4.00 for washing car. what was her weekly allowance if she had 12.00 left?

her weekly allowance= 16

Step-by-step explanation:

Imani spent half of her weekly allowance playing golf.

Let her weekly allowance be x

Imani spent x/2 playing golf.

Her parents gave her 4.00 for washing car. This means she has additional 4 .00 for washing car besides x

She has a total of x + 4

What was her weekly allowance if she had 12.00 left? This means after spending x/2 on playing golf, she still had 12.00 left from the total of (x +4)

That is

(x +4) - x/2 = 12

Taking LCM of 2 on the left hand side

2(x+4)-x =12

(2x + 8 - x)/2 =12

2x - x +8 = 12×2 = 24

x +8= 24

x = 24-8 = 16

her weekly allowance= 16

Check

16/2)+4 = 12(what she had left)

one set of data has more variation than the other. hope this !

the answer is 21%.
