Answer 1

Answer:

75.3% (1 d.p.)

Step-by-step explanation:

Percentage Change

$\sf percentage\:change=\dfrac{final\:value-initial\:value}{initial\:value} \times 100$

Given:

• initial value = £3.60
• final value = £6.31

$\begin{aligned}\implies \sf percentage\:change & =\dfrac{6.31-3.60}{3.60} \times 100\\\\& = \dfrac{2.71}{3.60} \times 100\\\\& = 75.277777... \%\end{aligned}$

Therefore, the percentage increase in the minimum wage was:

• 75.3% (1 d.p.)
