Answer 1

Amy needs to sell at least 27 computers for £400 each to get 35% more than the £8,000 she spent on purchasing 50 computers at £160 each.

Step-by-step explanation:

To work out the smallest number of computers Amy needs to sell to get at least 35% more than she paid for all the computers, we first need to calculate the total cost and then the desired total revenue.

Amy bought 50 computers at £160 each, so:

• Total cost = 50 × £160 = £8,000

She wants to get at least 35% more than £8,000, so:

• 35% of £8,000 = 0.35 × £8,000 = £2,800
• Desired total revenue = £8,000 + £2,800 = £10,800

If Amy sells each computer for £400, the smallest number of computers she needs to sell to meet her target is:

• £10,800 ÷ £400 = 27

Therefore, Amy needs to sell at least 27 computers for £400 each to achieve at least 35% more than the amount she paid for all the computers.

Answer 2

she need to sell 7 computers
