Answer:
Fernado saves $90.
Explanation:
40% of $150 ( original price ) = $60
$150 - $60 ( original price - discounted price ) = $90 ( savings )
The question asks about the 40% markdown only, so I'd assume you wouldn't reduce it by $25.
But if you did Fernando would save $115 :
40% of $150 ( original price ) = $60
$60 - $25 ( mail-in rebate ) = $35
$150 - $35 ( original price - discounted price ) = $115 ( savings )
