In 1999 the minimum wage for adults was £3.60 per hour.

Work out the percentage increase in the minimum wage.

Answer 1

75.3% (1 d.p.)

Explanation:

Percentage Change

`\sf percentage\:change=(final\:value-initial\:value)/(initial\:value) * 100`

Given:

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

`\begin{aligned}\implies \sf percentage\:change & =(6.31-3.60)/(3.60) * 100\\\\& = (2.71)/(3.60) * 100\\\\& = 75.277777... \%\end{aligned}`

Therefore, the percentage increase in the minimum wage was:

• 75.3% (1 d.p.)
