Carlton runs 3 miles each day from monday through friday. he runs 5 miles on saturday and 5 miles on sunday. he calculates that he will run 900 miles total in 41 weeks.

Carlton would have actually run 1025 miles and not 900 in 41 weeks.

Step-by-step explanation:

Total miles run by Carlton in one week includes 3 miles per day for five days ( Monday to Friday) and 5 miles per day for two days(Saturday and Sunday).

So the total miles in a week = 3 * 5 + 5 * 2 = 15 + 10 = 25

In 41 weeks, he would have run 41* 25 miles = 1025 miles

But as per Carlton's calculation, he would have run only 900 miles.

So we can conclude that Carlon's calculation is less than the actual number of miles run by 125.

A linear function has a constant rate of change, while a nonlinear function does not. For a table of values to be linear, the outputs must have a constant rate of change as the inputs increase by 1. On a graph, the function must be a straight line to be linear.
