dara spent 25% of his money in one shop , he spent 33 1/3 of the remainder and had £6.80 left , how much had he at first

x = 0.25x + 33 1/3 (0.25x) + 6.80

x = ?

find the value of both percentages out of 100 and then add them together along with the $6.80

55+99=154

To find out how much Dara had at first, we can follow these steps:

1. Let's assume that Dara had "x" amount of money at first.
2. Dara spent 25% of his money, which is 0.25x.
3. After spending 25%, Dara had (x - 0.25x) = 0.75x remaining.
4. Dara then spent 33 1/3% of the remaining amount, which is (1/3 + 1/3 + 1/3) × 0.75x = (3/3) × 0.75x = 2.25x/3.
5. After spending 33 1/3%, Dara had (0.75x - 2.25x/3) remaining.
6. We are told that he had £6.80 left, so we can write the equation: (0.75x - 2.25x/3) = 6.80.

To solve this equation and find the value of x, we can follow these steps:

1. Multiply through by 3 to eliminate the fraction: 3(0.75x) - 2.25x = 3(6.80).
2. Simplify the equation: 2.25x - 2.25x = 20.40.
3. Combine like terms: 0 = 20.40.
4. This equation does not have a valid solution, as zero cannot equal 20.40.

Therefore, there is no valid solution to this problem. Please double-check the given information to ensure its accuracy.
