Final answer:

The cheapest way to purchase 10 rolls of wallpaper is by buying 3 packs of 3 rolls plus one single roll, costing a total of £85.70.

Step-by-step explanation:

To find the cheapest price for 10 rolls of wallpaper, we need to compare the cost of buying single rolls, packs of 3, and packs of 5.

  • Buying 10 single rolls at £9.20 each would cost £92.00 (10 x £9.20).
  • Buying 3 packs of 3 rolls would give us 9 rolls at £25.50 per pack, with a total cost of £76.50 (3 x £25.50), plus one single roll at £9.20, adding up to a total cost of £85.70.
  • Buying 2 packs of 5 rolls would give us the 10 rolls needed at £43.05 per pack, totaling £86.10 (2 x £43.05).

After comparing all options, purchasing 3 packs of 3 rolls plus a single roll at £9.20 is the cheapest option, costing £85.70.
