Sue earns a 9% profit on each tin of green paint sold. In mixing 50 liters of green paint, the ratio of yellow to blue paint is 1:4. To figure out the quantity of yellow paint, you divide. For the blue paint, a similar calculation applies. With yellow paint sold in 5-liter tins priced at £38 each, she has a total of 10 liters, which means she possesses 2 tins costing £76. For the blue paint sold in 10-liter tins at £58 each, she has 40 liters implying 4 tins that cost £232. The total expense for yellow and blue paints amounts to £308. After selling the 50 liters of green paint in 10-liter tins at £89.32 each, she sells 5 tins for a total of £446.60. Consequently, the profit from selling all green paint results in a 45% return, establishing Sue's percentage profit for each tin at 9%.
