Explanation

0.30 * 680 = 204. 0.20 * 97 = 19.4. 204 + ? + 19.4 = 253 => 223.4 + ? = 253 => ? = 29.6. Closest is 30.

AI explanation

Round the numbers to estimate 30% of 679 plus the missing value, plus 20% of 97, equals 253. Calculate 30% of 679 as 203.7. Calculate 20% of 97 as 19.4. Substitute these values into the equation to get 203.7 plus the missing value, plus 19.4, equals 253. Add 203.7 and 19.4 to get 223.1, then subtract 223.1 from 253 to find the missing value of approximately 30.
