Question
The national minimum wage increased by 25% between 2010 and 2019. How does this compare to the percentage change in the price of crisps during the same period?
The price of crisps increased by 49%:
Percentage change = (67p 鈭 45p) 梅 45p 脳 100
22p 梅 45p 脳 100
49% (rounded up)
Since the price of crisps has increased at a faster pace than the national minimum wage, someone earning the national minimum wage between 2010 and 2019 has seen a reduction in their purchasing power for crisps.
\(\text{Percentage Price Change} = \frac{\text{2018 Price - 2010 Price}}{\text{2010 Price}}\times 100\)
\(\text{Percentage Price Change} = \frac{\text{67p - 45p}}{\text{45p}}\times 100\)
\(\text{Percentage Price Change = 04889}\times 100\)
\(Percentage Price Change = 49% (to 0 decimal places)\)
The impact of inflation on businesses
