<h3>What is addition?</h3>
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
