At the beginning of George’s diet, he weighed 212 pounds, and 8 weeks later he weighed 198 pounds. Find the average rate of change of George’s weight.

I think its 1.75 but also -1.75? which one could it be? Please help! Thanks!

  • Algebra -

    212 - 198 = 14

    14 / 8 = 1.75 -- so he lost an average of 1.75 pounds per week. That's about 0.8% of his original weight.

    Yea but they are looking for the rate of change. Wouldn't that be a negative number?

  • Algebra -

    Yes, the rate of change is -1.75 pounds per week. The negative sign is implied in the expression lost an average of 1.75 pounds per week.
