lets see.  make 200 muffins, 15% spoil so 15% of 200 = .15 times 200 = 30 spoil.  therefore they will sell 170 muffins.
it cost them .69 times 200 = $138 to make the 200 muffins and they want a 30% markup so they want to make 1.30 times $138 = $179.40

so the price per muffin should be 
$$]\frac{179.40}{170}=$1.055$$ or about $1.06 rounded
