Question

A laptop computer that you want to purchase was originally priced at $975. You will receive a 20% student
discount, and the sales tax rate is 8%. How much money will you pay for the laptop? Round to the nearest
cent if needed.
​

Answer 1

Answer:

842.4

Step-by-step explanation:

Alrighty, let;'s find what is 20 percent of 975.

20 percent is also 1/5 so 1/5 times 975 is 195

Discount would have 975-195 which is 780

Now we have sales tax which increasces the tax. Let's find what is 8 percent of 780. Let's do 0.08 times 780 which is 62.4

The total is 780+62.4= 842.4

Answer 2

$842 is the money that he will have to pay.

How to find the percentage of a number?

Finding the percentage of a number 'p', we have to multiply it by the percentage to be found divided by 100, so for example, 30% of p is equal to 0.3n.

What are discounts and sales taxes?

Discount is the amount of price that we have to pay less but the sales tax is the amount we have to pay more while purchasing the item, on the actual purchase price.

The solution to the problem

The price the student will have to pay after the discount is equal to 975-0.2*975 = $780.

Now while purchasing after the discounted amount he will have to pay the price of the laptop plus the sales taxes on it and hence he will have to pay 780+780*0.08 = $842.4, rounding the price to the nearest dollar we get $842.

Hence the total amount to be paid to purchase the laptop is $842.
