Luca’s coupon saved him 8 / 4 = $<<8/4=2>>2 on his sandwich.

He paid $1 for avocado on his sandwich, so the sandwich cost 8 - 2 + 1 = $<<8-2+1=7>>7.

He paid $3 for his salad, so his meal without the drink was 7 + 3 = $<<7+3=10>>10.

Thus, Luca paid 12 - 10 = $<<12-10=2>>2 for his drink.

Luca went to a sandwich shop for lunch. The sandwich he bought was normally $8, but he had a coupon for a quarter of the price off. He then upgraded it with sliced avocado for an extra dollar. After adding a drink and a $3 salad, his total lunch bill was $12. How many dollars did Luca pay for his drink?
