On cyber Monday a 40$ hard drive was discounted by 30%. If the tax rate in your city is 7%, what is the total cost of the hard d

Georgia [21]

The total cost of hard drive is $29.96

Step-by-step explanation:

Given,

Original price = $40

Discount = 30%

Discount amount = 30% of $40 = $\frac{30}{100}*40$

Discount amount= $\frac{1200}{100}= \$12$

Price after discount = Original price - discount amount

Price after discount = 40-12 = $28

Tax rate = 7%

Tax amount = 7% of price after discount

$Tax\ amount=\frac{7}{100}*28\\Tax\ amount=\frac{196}{100}\\Tax\ amount=\$1.96$

Total cost of hard drive = Price after discount + Tax amount

Total cost of hard drive = 28+1.96 = $29.96

The total cost of hard drive is $29.96
