An athlete is tracking his weight over several weeks. After 3 weeks
he weighs 188 pounds. After 6
weeks, he weighs 167 pounds.
What is his rate of change?

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.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
