Kiki likes to spend her money on hats and scarves. When she buys twice as many hats as scarves, she spends 60% of her money on hats and the rest on scarves. If she currently has $90, how many scarves will she buy if they are sold at $2 each?
Step-by-step reasoning process below:
18
Kiki spends 60 / 100 * $90 = $54 of her money on hats.

The amount she spends on buying scarves is $90 - $54 = $36.

If each scarf is sold at $2, Kiki will buy $36 / $2 = 18 scarves.

.

Therefore, the answer is 18
