Answer:
$42.51
Step-by-step explanation:
markup percentage = (selling price - cost) / cost
54% = (selling price - $27.60) / $27.60
54% x $27.60 = selling price - $27.60
$14.904 = selling price - $27.60
selling price = $42.504 ≈ $42.51 we must round up since we are looking for the price that would yield the markup %, if we round down, then the markup % would be slightly below 54%
