Beth had a set of 125 gold coins.  Carl gave Beth a gift of an additional 35 gold coins.  Then, Beth decided to sell half of her coins.  How many coins did Beth sell?
Carl's gift added 35 gold coins to Beth's 125-coin set, resulting in 135+25=160 gold coins.
Beth chooses to sell half, or 160/2=<<160/2=80>>80 of her gold coins.
