What is the calculation for finding the total investment if $3078 represents 17% of that total?

3078 / 0.17
3078 + 0.17
3078 * 0.17
3078 - 0.17

The correct answer is: 3078 / 0.17

To find the total investment when $3078 represents 17% of that total, you can use the formula for calculating a value from a percentage. In this case, you want to determine what the whole amount is when you know a part of it (which is 17%). The relationship between a percentage and the whole is expressed as follows: if a certain amount (in this case, $3078) is a specific percentage (17%) of a whole, you can find that whole by dividing the part by the percentage expressed as a decimal. The decimal equivalent of 17% is 0.17. Therefore, to find the total investment, you set up the calculation as: Total Investment = Amount / Percentage Total Investment = $3078 / 0.17 This calculation accurately reveals the total investment, giving you the complete picture of how much that $3078 represents in relation to the whole sum. The other options would not yield the correct total investment. For example, simply adding 0.17 to $3078 does not relate to the calculation of percentages. Likewise, multiplying by 0.17 or subtracting 0.17 does not produce the needed total; these operations do not align with calculating the total
