Final answer:
The equation for "C", in terms of "t", representing the number of chocolates remaining in the box "t" days after Chloe was given the box is C = 30 - 2t.
Step-by-step explanation:
The equation for "C", in terms of "t", representing the number of chocolates remaining in the box "t" days after Chloe was given the box is C = 30 - 2t. This equation takes into account that Chloe eats some chocolates each night. The original number of chocolates (30) is subtracted by twice the number of days (2t) to find the remaining number of chocolates in the box.
