If she buys 1 toy at $12.00 she gets the 2nd toy 1/2 off, the 2nd toy is 12*.5 = $<<12*.5=6.00>>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 = $<<12+6=18.00>>18.00

She buys 2 more toys that are "buy one get one 1/2 off" so all total she spends 2*18 = $<<2*18=36.00>>36.00
