Question 1: A trader pays 80 dollars for a cake maker after a discount of 15 dollars. Find the original price of the cake maker?
Solution:
Let x be the original price.

x - 15 = 80

Take +15 on both the sides

x - 15 + 15 = 80 + 15

x + 0 = 95

x = 95

The original price for cake maker is 95.

$(\frac{1}{2})x + 5 - 5 = 21 -12$

$(\frac{1}{3})x = 9$

x = 27
