A130

B120

C150

D140

Answer:

D. 140

Read Explanation:

To find the average, we use the formula:

Average=Sum of numbersNumber of numbers\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.

Average=7005=140\text{Average} = \frac{700}{5} = 140

Answer: 140
