[Question]: The dog toys Samantha buys for her dog are "buy one get one half off" and all cost $12.00 each. She buys 4 toys. How much does she spend on dog toys?
[Answer]: If she buys 1 toy at $12.00 she gets the 2nd toy 1 / 2 off, the 2nd toy is 12 * .5 = $6.00. 1 full - priced toy is $12.00 and 1 / 2 priced toy is $6.00 so these 2 toys come to 12 + 6 = $18.00. She buys 2 more toys that are "buy one get one 1 / 2 off" so all total she spends 2 * 18 = $36.00.
So the answer is 36.
