A restaurant sold a total of 316 large and small hamburgers one day the total hamburger sales were $1, 245. Large hamburgers sold for $3, and small hamburger sold for $1.20. Which system of linear equations can be used to find L, the number of large hamburger sold, and S, the number of small Burgers sold?

• L + S = 316

  3L + 1.2S = 1,245

• 1.2L + 3S = 316

  L + S = 1,245

• 1.2L + 3S = 1,245

  L + S = 316

• L + S = 1,245

  3L + 1.2S = 316
