Answer:
a) Avg rate of change = 4 pounds per week
b) 160 pounds
Step-by-step explanation:
a)
The average rate of change is also called the slope. It is advertised that a person can loose 4 pounds in a week in the program. So, the average rate of change is 4 pounds per week.
Avg rate of change = 4 pounds per week
b)
In 5 weeks, a person can loose:
4 * 5 = 20 pounds (in 5 weeks)
Initially the person weighed 180 pounds, now after the program, he lost 20 pounds, so his weight will be:
180 - 20 = <u>160 pounds</u>
