A glacier that was 1,076 meters thick changed in thickness at an average rate of -22.7 meters per year for 7 years.
a)Write an addition expression you can use to find the glacier's thickness after 7 years.
b)Evaluate your expression.
Thank you for your help.



Answer :

1,076 (the original thickness) - 22.7 meters (loss per year) * 7 (lost 22.7 meters per year for seven years, so multiply the loss per year by the amount of years) = 917.1 (the size after 7 years)

A.K.A  1,076 - 22.7 * 7 = 917.1
A) 1,076 - 22.7(7) is the expression :)

B) after 7 years it equals 917.1 m thick :)
