[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.

[Question]: A school canteen sells a sandwich at $2, a hamburger at $2, one stick of hotdog at $1, and a can of fruit juice at $2 each can. Selene buys three sandwiches and a can of fruit juice. Tanya buys two hamburgers and two cans of fruit juice. How much do Selene and Tanya spend together?
[Answer]: Three sandwiches cost 3 x $2 = $6. So, Selene spends $6 + $2 = $8. Two hamburgers cost 2 x $2 = $4. Two cans of fruit juice cost 2 x $2 = $4. Thus, Tanyah spends $4 + $4 = $8. Therefore, Selene and Tanya spend $8 + $8 = $16.
So the answer is 16.

[Question]: Perry, Dana, Charlie, and Phil played golf together every week. At the end of the season, Perry had won five more games than Dana, but Charlie had won 2 games fewer than Dana. Phil had won 3 games more than Charlie did. If Phil won a total of 12 games, how many more games did Perry win than did Phil?
[Answer]:
If Phil had won 3 games more than did Charlie, and Phil won 12 games, then Charlie won 12 - 3 = 9 games. If Charlie had won 2 games fewer than Dana, and Charlie won 9 games, then Dana won 9 + 2 = 11 games. If Perry had won five more games than did Dana, and Dana won 11 games, then Perry won 11 + 5 = 16 games. Thus, Perry won 16 - 12 = 4 more games than did Phil.
So the answer is 4.
