Afini spent 20% of $90 on sandals, which is 0.20 x $90 = $18.
So, she had $90 - $18 = $72 left.
She then spent 11% of $72 on a skirt, which is 0.11 x $72 = $7.92.
Therefore, she had $72 - $7.92 = $64.08 left after buying the skirt.
Afini had $90. She spent 20% of her money on a pair of sandals and 11% of the remainder on a skirt. How much money had she left?
