Quarterly changes in population are converted to an annual change by multiplying growth factors. A
growth factor = 1 + i where i is the percentage increase given in decimal form.
The four quarterly increases in the number of staff employed by a particular company last year were
5.6%, 2.1%, – 3% and 1.4%.
To one decimal place, what was the total percentage increase in staff numbers for that year?
