Final answer:
To get the cost of 10 liters of paint from each shop, calculate the cost for each shop separately. Choose Paint Supplies for the lowest cost.
Step-by-step explanation:
To find the cost of getting 10 liters of paint from each shop, we need to consider the prices and offers of each shop. Let's calculate the cost for each shop:
Home Stores:
Home Stores sells 2 tins of paint for £4.40 each. So, for 10 liters, we need 10/2 = 5 tins. The cost would be 5 x £4.40 = £22.
Paint Supplies:
Paint Supplies sells 1 tin of paint for £3.10. If it's 3 for 2, then for 10 liters, we need 10/1 = 10 tins. However, since it's 3 for 2, we only need 10/3 = 3 sets of 3 tins. The cost would be 3 x £3.10 x 2 = £18.60.
The DIY Shop:
The DIY shop sells 2.5 tins of paint for £7.10 each, and it's buy 3 get 1 free. So, for 10 liters, we need 10/2.5 = 4 sets of 3 tins. Since we get 1 free for each set, we only need to buy 4 x 3 = 12 tins. The cost would be 12 x £7.10 = £85.20.
In summary, the cost of getting 10 liters of paint from each shop is:
- Home Stores: £22
- Paint Supplies: £18.60
- The DIY Shop: £85.20
Carly should choose Paint Supplies as it offers the lowest cost for getting 10 liters of paint.
