Question

The average high temperature for the week below was 65 degrees. What was the temperature Wednesday? A. 65B. 56C. 72D. None of the aboveI will appreciate the help

Answer 1

Since the average high temperature is 65

Average = sum / n

N = no of days

n = 5

65 = 76 + 70 + x + 68 + 55 / 5

Introduce cross multiplication

65 * 5 = 76 + 70 + x + 68 + 55

325 = 269 + x

Make x the subject of the formula

x = 325 - 269

x = 56

The answer is 56
