  2. Page 126 • 5) step 1: Find rule for both options • Y = 30x + 720 y = 60x • step 2: Use comparison • 30x + 720 = 60x  x = 24 • step 3: find y (replace x value in either equation)  y = 1440

  3. Page 126 • 6) • A) t = time (independent) • V = volume (dependent) • B) v = -10t + 300 • v = 10t + 100 • D) 1. after 10 minutes • 2. after 5 minutes • 3. after 30 minutes

  4. Page 127 • 7a)x: amount of sales • Y: total salary ($) • Option 1: 10% of the amount of sales and $100 base salary (y = 0.1x + 100) • Option 2:5% of the amount of sales and $300 base salary (y = 0.05x + 300)

  5. Page 127 • 7b) x: number of photos • y: total cost ($) • Option 1: each photo costs $5 (y = 5x) • Option 2: each photo costs $2 and the fixed cost is $50 (y = 2x + 50)

  6. Page 127 • 7c)x: times in hours • y: number of litres in the tank • Tank 1: contains 6000 L at the start and it empties at a rate of 1000L per hour (y = 6000 – 1000x) • Tank 2: contains 4000 L at the start and it empties at a rate of 500 L per hour. (y = 4000 – 500x)
