Step-by-step explanation:
Part = (percent) whole
x = (3.5) 5
x = $17.5 <------- regular price
x = (.7) 17.5
x = $12.25 <--------- marked down price
Percentage is a way to describe a part of a whole. The sale price of the calculator whose original price was $5 is $12.25.
What is Percentage?
A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
We know that the original price of the calculator is $5, and when the price of the calculator is marked it is 350% of the original value. therefore, the marked up price of the calculator can be given as,
[tex]350\% of\ \$ 5 \\\\= \dfrac{350}{100}\times 5\\\\= \$17.5[/tex]
Thus, the marked-up price of the calculator is $17.5.
Now, as the store gives a 30% discount on the marked-up value of the calculator, therefore, the price of the calculator will be 70% of the marked up price of the calculator,
[tex]70\% of\ \$ 17.5 \\\\= \dfrac{70}{100}\times 17.5\\\\= \$12.25[/tex]
Hence, the sale price of the calculator whose original price was $5 is $12.25.
