Answer:
To calculate the increase in average monthly income after joining the project, we first need to determine the total income before and after your participation. Then, we will calculate the average monthly increase.
Total income before participation:
Month 1: £4,420
Month 2: £4760
Total before your participation: £4,420 + £4,760 = £9,180
Total income after participation:
Month 2: £4760
Month 3: £6,120
Month 4: £5,950
Total after your participation: £4,760 + £6,120 + £5,950 = £16,830
Now, we calculate the total increase in monthly income:
Total increase = Total income after your participation - Total income before your participation
Total increase = £16,830 - £9,180 = £7,650
To find the average monthly increase, we divide the total increase by the number of months you were involved in the project:
Average monthly increase = Total increase / Number of months
Average monthly increase = £7650 / 3 months = £2550
Therefore, after joining the project, the average monthly income increased by £2,550.
