repairing it and sold it for £18. Calculate the gain

percent on his total costs. (to nearest %)

Help

Answer:Profit % = 39%

Step-by-step explanation:Cost price of the article = 9

Price for repairing = 4

Therefore, Total cost of the article = 9 + 4 = 13

Selling price of the article = 18

Profit = 18 – 13 = 5

Hence,

[tex]Profit \% = \frac{Profit}{Cost \ price} \times 100\\\\[/tex]

[tex]= \frac{5}{13} \times 100\\\\=38.46 \%\\\\=38.5 \%[/tex]

Profit percent (to the nearest %) = 39%
