Question

The line graph below shows the total costs and total sales of a company for each year from $2012$ to $2022$.

Find the percentage increase of the company’s total annual costs and total annual sales from $2012$ to $2022$, respectively.

The table below shows the profit and profit rate of the company for each year from $2012$ to $2022$.

Complete the table, correcting your answers to $3$ significant figures for profit rate.

Year	2012	2013	2014	2015	2016	2017	2018	2019	2020	2021	2022
Profit ($ million)	0.3	0.4	0.6	0.8	1.3	1.1	0.8	0.7
Profit Rate (%)	60.0	50.0	42.9	27.6	35.1	27.5	19.0	15.2

Hence find the greatest annual profit and the greatest annual profit rate of the company from $2012$ to $2022$, and state the year(s) when these values occur.
Hence complete the line graph below and state the year(s) when the company had an annual profit loss.
