Answer:
Step-by-step explanation:
a. Andy = £9500
Bevan = £25000
Cheryl = £11250
Deva = £72000
Elliott = £12750
Frankie = £29500
Grace = £11000
Total Income = £171,000
To get the mean Income, we divide the total income gotten by 6 which is the number of people. This will be:
= £171,000/7
= £24428.57
b. If Deva's income is excluded, there'll be 6 people left.
Andy = £9500
Bevan = £25000
Cheryl = £11250
Elliott = £12750
Frankie = £29500
Grace = £11000
Total income = £99000
Mean income = £99,000/6
= £16,500
