Question
Ms Kay bought a roll of lace. She used 40% of it to make dresses and 25% of the remainder on skirts. She used 30 m more lace on the dresses than on the skirts. What was the length of the roll of lace Ms Kay have?
Solution
Let's denote the total length of the lace roll as X meters.
- Ms Kay used 40% of the lace roll for dresses, which is 0.4X meters.
- The remainder of the lace roll is then 60% of the total, which is 0.6X meters.
- She used 25% of this remainder on skirts, which is 0.25 * 0.6X = 0.15X meters.
- According to the problem, she used 30 m more lace on the dresses than on the skirts. So, 0.4X = 0.15X + 30.
- Solving this equation for X gives X = 30 / (0.4 - 0.15) = 120 meters.
So, the total length of the lace roll Ms Kay had was 120 meters.
