Notebooks cost $ 1.20 each. This weekend they will be on sale for $ 0.80. What percentage is the sale

Mathematics

Rainbow [258]4 years ago

From the information we have, we know that each book costs 1.20 dollars. So we shall say this price is at 100% .

Now we need to form an equation to get the percentage  when the books are sold at 0.80 dollars.

100% = 1.20

       x = 0. 80

Where x is the new percentage when the sale is at 0.80 dollars.

We cross multiply the equation:

1.20 *x = 0.80 * 100

1.2x = 80

x = 80/1.2

x = 66.7%

Round off 66.7 to the nearest tenth we get 67%

The notebooks are sold at 67% (of the original cost).

Alice Smith bought a clothes dryer that retailed for $325 . She received a 15% discount because she works at the store where she
r-ruslan [8.4K]

Answer:

296.97

Step-by-step explanation:

Remark

The first thing you have to realize is that you take the discount before you add the sales tax.

Discount

If she receives a 15% discount, she still pays 85% of the full price.

85/100 * 325 = 276.25

Sales Tax

A sales tax is only added on after a goods or service has been determined and agreed upon by the buyer and seller.

The sales tax can be calculated quickly by adding the decimal equivalent onto 1 and multiplying that by the discounted amount.

1 + 7.5% = 1 + 7.5/100 = 1 + 0.075 = 1.075     deriving the discount amount

Cost

Cost = discounted price * 1.075                    Substitute in Formula

Cost = 276.25 * 1.075                                    Simplify

Cost = 296.97                                                Answer
