Final answer:
To find the original number before a 130% increase resulting in $184, divide $184 by 2.3, giving an original number of approximately $80.
Step-by-step explanation:
The question asks to find the original number that, when increased by 130%, results in $184. To solve this, we use the following steps:
Understand that 130% more than a number means the final amount is 230% of the original number (since 100% + 130% = 230%).
Convert the percentage to a decimal by dividing by 100, getting 2.3.
Divide the final number ($184) by 2.3 to find the original number.
So the calculation is $184 ÷ 2.3, which gives us the original number the student is seeking.
By performing this division, we find that the original number is approximately $80.
