REAL LIFE PROBLEM

• A man was very overweight and his doctor told him to lose 36 kg. If he loses 11 kg the first week, 9 kg the second week, and 7 kg the third week, and he continues losing at this rate, how long will it take him to lose 36 kg? (Hint: Look for a pattern. Then complete the table.)

WEEK TOTAL KG LOST1 112 11+9 = 203 20+7 = 2745

UNDERSTANDING THE PROBLEM

• How much does the man need to lose? (36 kg) · How much did he lose the first week? (11 kg) · How much did he lose the second week? (9 kg) · How much did he lose the third week? (7 kg)

PLANNING A SOLUTION

• How much less does he lose the second week than the first week? (2 kg)• How much less does he lose the

third week than the secornd? (2 kg)

FINDING THE ANSWER

• Make a Table/ Look for a Pattern

WEEK TOTAL KG LOST1 112 11 + 9 = 203 20 + 7 = 274 27 + 5 = 325 32 + 3 = 356 35 + 1 = 36

• Pattern: The number of kilograms lost decreases by 2 each week. • It will take the man 6 weeks to lose

36 kg.
