Laura mowed 8 lawns. She earned $12, $10, $15, $15, $15, $10, and $9 for seven lawns. How much did she earn the eighth time if the mean of the data is $12? *

She earned $10 for mowing the 8th lawn.

Step-by-step explanation:

Let's use the average formula and n = 8, with x representing the 8th score:

                         12 + 10 + 15 + 15 + 15 + 10 + 9 + x

average = 12 =

                                                  8

                                                                              86 + x

Summing up the numerator, we get average = = 12

                                                                                   8

Multiplying both sides by 8 yields                          86 + x = 96

Solving for x, we get x = 10.

She earned $10 for mowing the 8th lawn.
