110 large bags and 170 small bags of popcorn were sold.

Step-by-step explanation:

Since yesterday a movie theater sold 280 bags of popcorn, and a large bag of popcorn costs $ 4 while a small bag of popcorn costs $ 1 and in all, the movie theater made $ 610 from popcorn sales, to find how many bags of each size of popcorn were sold, the following calculation must be performed:

280 x 4 + 0 x 1 = 1120

140 x 4 + 140 x 1 = 700

130 x 4 + 150 x 1 = 670

110 x 4 + 170 x 1 = 610

Therefore, 110 large bags and 170 small bags of popcorn were sold.
