Weekly allowance = $12.

Step-by-step explanation:

Let x be the weakly allowance.

She spent half of it on mini-golf,

Half of weakly allowance = $\frac{x}{2}$

and earned $9 from her parents,

$\frac{x}{2} + 9$

and ended the week with $15, so

$\frac{x}{2} + 9 = 15$

Solve above equation for x

$\frac{x}{2} + 9 = 15$

$\frac{x}{2} = 15 - 9$

$\frac{x}{2} = 6$

x=12

Therefore, Her weekly allowance is $12.
