Question

Laura is bowling 5 games. Her first 4 scores were 103, 143, 101, and 110.

Answer 1

Answer:

The least 5th score is 177

Step-by-step explanation:

Given

$First\ 4: 103, 143, 101, 110.$

$Average = 126.8$

Required

The least 5th score

Represent the 5th score with x.

The average is calculated as:

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

So, we have:

$126.8 = \frac{103 + 143 + 101 + 110 + x}{5}$

$126.8 = \frac{457 + x}{5}$

Multiply both sides by 5

$634= 457 + x$

Solve for x

$x = 634- 457$

$x = 177$
