Juwan has a third quiz in math on Friday. His two previous quiz grades were 85 and 72. What must he make on the third quiz for h
VLD [36.1K]

Answer:

x = 107

Step-by-step explanation:

Given

Scores = 85\ and\ 72

Average = 88

Required

Determine the third score

Average is calculated using;

Average = \frac{\sum x}{n}

In this case:

n = 3

Average = \frac{\sum x}{n}

Let the third score be x; So:

Average = \frac{85 + 72 + x}{3}

Substitute 88 for Average

88 = \frac{85 + 72 + x}{3}

88 = \frac{157 + x}{3}

Multiply through by 3

3 * 88 = \frac{157 + x}{3} * 3

264 = 157 + x

x = 264 - 157

x = 107
