If John had to mow 8 lawns, but he forgot to mow 2 lawns, we have to subtract 2 from 8 to see how many lawns he actually mowed.
8-2=6
John mowed 6 lawns!
For each lawn John mowed, he earned 3 dollars. So, we have to multiply the number of lawns he mowed, 6, by the amount of dollars he earned per lawn, 3. Multiplying 6*3 is the same as adding 3+3+3+3+3+3!
6*3=18
John earned $18!

Answer:
The mean weight of the cats is 11.42 (rounded)
Step-by-step explanation:
To find the mean, you add up all the weights (12, 12, 9, 9, 11, 11, 16) and then divided the sum (80) of the weights by the number of cats (7)
12+12+9+9+11+11+16= 80
80 ÷ 7= 11.42857143 (I rounded my answer to 11.42)
