Final answer:
The Good Haven Church now has two dozen boxes of offering envelopes, which can be expressed as the improper fraction 2/1.
Step-by-step explanation:
The Good Haven Church starts with a dozen boxes of offering envelopes and then they order a dozen more. Since a dozen is a group of 12 objects, we need to simply add the two groups of dozens together.
A dozen plus another dozen is two dozen. In numerical form, this is 12 + 12, which equals 24. But since the question asks for an answer in the form of an improper fraction representing dozens, we represent two dozen as 24/12, which simplifies to 2/1 or just 2 when expressing in terms of dozens.
The Good Haven Church now has two dozen boxes of offering envelopes, which can be expressed as the improper fraction 2/1.
