Colton was given a box of assorted chocolates for his birthday. Each night, Colton treated himself to some chocolates. There were originally 30 chocolates in the box and Colton ate 2 chocolates each night. Write an equation for C, C, in terms of t, t, representing the number of chocolates remaining in the box tt days after Colton's birthday.

Given:

Initial number of chocolates in the box = 30

Colton ate 2 chocolates each night.

To find:

The equation for the number of chocolates remaining in the box t days after Colton's birthday.

Solution:

Let C be the chocolates remaining in the box and t is number of days after Colton's birthday.

Colton ate 2 chocolates each night. It means, the remaining number of chocolates decreased by 2 per day.

Initial number of chocolates in the box is 30 and it decreased by 2 per day. So, the equation for remaining chocolates is

Therefore, the required equation is .
