  3. Jerry made a profit of $320 selling snack bars at a bike race. If the total sales were $1000 and the snack bars cost him $2 each, how many did he sell? Profit = Income - Expenses 320 = 1000 - 2x -1000 -1000 -680 = -2x -2 -2 He sold 340 snack bars. 340 = x

  6. The population in Falls Creek was 34,000 this year. If the population decreases at 1250 people per year, in how many years will the population be 14,000? Let x = # of years 34,000 - 1250x = 14,000 -34,000 -34,000 - 1250x = -20,000 - 1250 -1250 x = 20 In 20 years
