Question: 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? Think carefully first, then make a decision:
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. So the answer is 18.
