Answer:
His rate of change is 7 pounds per week.
Step-by-step explanation:
Rate of change = change in weight ÷ change in time
change in weight = 188 - 167 = 21 pounds
change in time = 6 - 3 = 3 weeks
Rate of change = 21 ÷ 3 = 7 pounds/week
Answer:
He loses 7 pounds per week
Step-by-step explanation:
After 3 weeks he weighs 188 pounds.
After 6 weeks he weighs 167 pounds.
Weight loss = (188 - 167) pounds = 21 pounds
Time interval = 6 weeks - 3 weeks = 3 weeks
Rate of change = Weight loss ÷ time interval = 
pounds per week = 7 pounds loss per week.
