During the Christmas season, a store offers a sale. You buy one item for the regular price then you get 60% discount on a second
Lelu [443]

Answer:

24%

Step-by-step explanation:

Given: Regular price of two item is $30 and $20.

           60% discount provided on second item.

Now, lets find out discount provided on second item.

∴Discount provided = \frac{60}{100} \times 20 = \$ 12

Amount paid for second item = Regular price - discount provided

∴Amount paid on second item= 20 - 12= $8

Total amount paid for two item= Regular price of first item + discounted price of second item.

∴Total amount paid for two item= 30+8= \$ 38

Next, lets find out the percent of reduced total cost of two item.

\frac{reduced\ amount}{total\ regular\ price} \times 100

\frac{12}{50} \times 100 = 24\%

∴ By 24\% the total cost of two item reduce during sale.
