Write an expression that can be used to find the sale price of any pastry in the bakery. Kimberly bought a pastry on sale at the bakery. The sale price of the pastry was $2.03. What was the regular price of the pastry? (Round your answer to the nearest cent.) Be sure to show your work using the equation you created.

Answer 1

a) The expression to find the sale price of pastry = 0.75 x

b) The regular price of the pastry bought by Kimberly = $2.70

Explanation:

Step 1 :

Let x be the regular price of the pastry in the bakery

Percentage of discount = 25%

Amount of discount = 0.25 x

The expression to find the sale price of pastry = x - 0.25 x = 0.75 x

Step 2 :

Sale price of the pastry bought by Kimberly = $2.03 = 0.75 x

To find the regular price

0.75x = 2.03

x =
`(2.03)/(0.75)` = 2.70

Regular price of the pastry bought by Kimberly = $2.70

Step 3 :

Answer :

a) The expression to find the sale price of pastry = 0.75 x

b) The regular price of the pastry bought by Kimberly = $2.70
