Question

sal recorded the outdoor temperature as -4°F at 7:30 am . at noon , it was 22°F . sal said the temperature changed by 18°F because 22-4=18. Is sal right or wrong .

Answer 1

Sal was wrong as the change of temperature is 26°F

Explanation:

recorded temperature at 7:30 A.M. = -4°F

at noon = 22°F

change of temperature = 22 - (-4) = 26°F

therefore, Sal was wrong as the change of temperature is 26°F

Answer 2

• Sal is wrong, correct answer is 26°F

Explanation:

• Initial temperature = -4°F
• Temperature at noon = 22°F

Temperature change:

• 22 - (-4) = 22 + 4 = 26°F

Sal is wrong as the difference should be calculated as subtraction of the two values and absolute value of the result should be taken as the answer
