Elise is a project manager.

KengaRu [80]

$\text{In 2016, Elise earned a monthly salary of }\pounds 2100\\
\text{and in 2017, she earned a }3\% \text{ pay increase on her monthly salary.}\\
\text{so her increased monthly salary in 2017 is}=2100+3\% \text{ of 2100}\\
\\
=2100+0.03(2100)\\
\\
=2100+63\\
\\
=\pounds 2163\\
\\
\text{now given that in 2017 Elise worked 42 hours per week for 45 weeks.}\\
\text{so the total number of hours she worked in 2017 is}=42\times 45=1890\text{ hours}$

$\text{And the total earning of Elise in 2017}=2163\times 12=\pounds 25956\\
\\
\text{So her average per per hour in 2017 is}=\frac{25956}{1890}\approx \pounds 13.73$
