3. A restaurant sold a total of 418 large and small hamburgers during one day. Total hamburger sales were $1077. Large hamburgers sold for $3, and small hamburgers sold for $1.50. Which system of linear equations can be used to find l, the number of large hamburgers sold, and s, the number of small hamburgers sold? A l + s = 1077 C 1.50l + 3s = 418 3l + 1.50s = 418 l + s = 1077 B l + s = 418 Dl + s = 418 3l + 1.50s = 10771.50l + 3s = 1077

4. What is the y intercept of 12y = 144x – 36?

5. Which is the solution to this pair of linear equations? 5y − 2x = 6 3x − 2y = 13  A (3, −2)  B (5, −2)  C (7, 4)  D (8, −4)

6. An investor has a total of 45 one-ounce ingots, made of either gold or silver, worth $7636.50. The value of a gold ingot is $280.00, and the value of a silver ingot is $4.25. Which system of equations can be used to find g, the number of gold ingots, and s, the number of silver ingots? A g − s = 45 C g + s = 45 280.00g + 4.25s = 7636.50 4.25g + 280.00s = 7636.50 B g + s = 45 D g − s = 7636.50 280.00g + 4.25s = 7636.50 280.00g + 4.25s = 45
