What is addition?

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

a.

Andy = £9500

Bevan = £25000

Cheryl = £11250

Elliott = £12750

Frankie = £29500

Grace = £11000

Deva = £72000

Total Income = £166,000

To get the mean Income, we will divide the total income by 6 which is the number of people.

= £166,000/7

= £23714.28

b. If Deva's income is excluded, there'll be 6 people left.

Total income = £99000

Mean income = £99,000/6

= £16,500

a) The mean income to 2 DP is £23714.28. b. If Deva's income is excluded, then the mean income will be £16,500.
