Question

• A. 130
• B. 120
• C. 150
• D. 140

Answer 1

Answer:

D. 140

To find the average, we use the formula:

$\text{Average} = \frac{\text{Sum of numbers}}{\text{Number of numbers}}$

Numbers: 300, 129, 49, 120, 102

Sum the numbers

• 300 + 129 = 429

• 429 + 49 = 478

• 478 + 120 = 598

• 598 + 102 = 700

• Divide by the number of numbers

There are 5 numbers.

$\text{Average} = \frac{700}{5} = 140$

Answer: 140
