George bought some food for his trip: a bottle of juice, a sandwich, and a bottle of milk. The sandwich was for $4, and the juice was two times more expensive. The bottle of milk cost was 75% of the total cost of the sandwich and juice. How much did George pay for his food?

How much did the juice cost? ** The juice was two times more expensive than the sandwich, so it was 4 * 2 = $<<2*4=8>>8.
How much did the juice and sandwich cost in total? ** The juice and the sandwich in total were a cost of 4 + 8 = $<<4+8=12>>12.
How much did the bottle of milk cost? ** So the cost of one bottle of milk was 75/100 * 12 = $<<75/100*12=9>>9.
How much did George pay for his food? ** In total for all the food, George paid 12 + 9 = $<<12+9=21>>21.
