Question

4. A department store recently had a big sale where the prices of

items were marked 25% off of the regular price. Now that the
sale is over, Tremain needs to mark each of the items back up
to its original price. The items and their sale prices are listed in
the table. Help Tremain complete the table.

Answer 1

The original prices for the listed items in the table are ; $30, $45, $74.935, $373.75 and $199.9375 respectively.

Using the parameters given for our Calculation;

• Mark off percentage = 25%

The original prices would be ;

• (1 + 0.25) × sales price

Now we have ;

Sales price = $24

Original price = 1.25 × 24 = $30

Sales price = $36

Original price = 1.25 × 36 = $45

Sales price = $59.95

Original price = 1.25 × 59.95 = $74.9375

Sales price = $299

Original price = 1.25 × 299 = $373.75

Sales price = $159.95

Original price = 1.25 × 159.95 = $199.9375
