My guess for 7 is around $30. For 8: 36. 9: 161. And for 10: 6. I got those by adding the whole numbers together and if the decimal was 7, 8, or 9 adding 1 :) I hope this helps

7.) By clusterring $7.04 + $5.95 + $6.08 + $5.06 + $6.12 = $6.00 + $6.00 + $6.00 + $6.00 + $6.00 = $30.00

8.) 9.3 + 8.7 + 8.91 + 9.052 = 9 + 9 + 9 + 9 = 36

9.) 37.6 + 44.1 + 41 + 39.1 = 40 + 40 + 40 + 40 = 160

In clustering method you look for a whole number usually ending with 0 which all the given numbers "clustered" around.
