Question

7. A shirt marked at $600 is sold at 30% off.

(a) Find the selling price of the shirt.
(b) If the shirt is sold at a profit of 5%, find the cost pric​

Answer 1

a) $420 b) $399

Explanation:

a) $600 = 100%

$60 = 10%

$60 times 3 gives 30% = $180

$600 - $180 = $420

b) $420 = 100%

$42 = 10%

$21 = 5%

this means, they profitted by $21.

so $420 - $21 = $399

therefore, $399 is the cost price
