Question

Select the situation in which one quantity is changing at a constant rate in relation to the other quantity.

Barry spends $9 on lunch daily.
The market value of a new computer decreases by 6% every year.
Nathan's investments increase in value by 13.5% each month.
The number of ants in a colony doubles every 8 weeks.

Answer 1

The number of ants in a colony doubles every 8 weeks.

Constant rate of change means that when the value of x increases, the y remains constant. So there is no change in the y value. In this case, the x value is the "week" and the y value is the "amount of ants".
