When 80 is subtracted from 20% of a number, the result is 30. What is the value of the number?

330

440

550

220

- Let's define the unknown number as \( x \).

- 20% of this number is \( 0.2x \).

- Subtracting 80 from \( 0.2x \) gives us 30.

- We write the equation: \( 0.2x - 80 = 30 \).

- Solving it, we first add 80 to both sides: \( 0.2x = 110 \).

- Next, we divide both sides by 0.2 to get \( x = 550 \).

- Compare with the options:

- Option 1: 330

- Option 2: 440

- Option 3: 550

- Option 4: 220

Answer: Option 3 (550) is correct.
