Percentages, SM-Bank 011

Brittany is an apprentice hair dresser who works 8 hours per day.

Yesterday she spent her time in the following way.

    • 0.42 of her day \(\rightarrow\) sweeping and tidying the salon
    • 0.18 of her day \(\rightarrow\) washing hair
    • 0.05 of her day \(\rightarrow\) drying hair

The rest of Brittany's day was spent restocking the shelves with new products.

What percentage of Brittany's day was spent restocking shelves?  (2 marks)

Show Answers Only

\(35\text{%}\)

Show Worked Solution
\(\text{Percentage of day restocking shelves}\) \(=1-(0.42+0.18+0.05)\)
  \(=1-0.65=0.35=35\text{%}\)

 

\(\therefore\ \text{Brittany spent 35% of her day restocking shelves.}\)
