To find the resulting number after increasing 80 by 120%, you multiply 80 by 1.2 to get 96 and add it to the original 80 to get the final answer of 176.
To calculate the resulting number after an increase of 120 percent, you must first understand what this percentage increase means. A 120% increase implies that the original number (80 in this case) will have its value increased by 120% of itself. This is calculated by multiplying the original number by the percentage increase, converted into decimal form, and then adding it to the original number.
First, convert the percentage to a decimal: 120% = 1.2. Next, calculate the increase by multiplying 80 by 1.2, which yields 96. Finally, add this increase to the original number: 80 + 96 = 176.
The resulting number after an increase of 120 percent to 80 is therefore 176.
Conclusion: When 80 is increased by 120%, the final number is 176.
