Sammy buys his clothes at super discounts. On saturday he bought shoes regularly priced at $40 for 25% off, and jacket regularly

Georgia [21]

Answer:

A. $100

B. 29%

Step-by-step explanation:

A. To find total price of the items Sammy bought we will add the price of shoes and jacket after discount.

Let us find price of shoes after 25% discount.

$\text{Price of shoes after discount}=40-(\frac{25}{100}*40)$

$\text{Price of shoes after discount}=40-(\frac{1}{4}*40)$

$\text{Price of shoes after discount}=40-10=30$

Therefore, price of shoes after discount is $30.

Now let us find price of jacket after 30% discount.

$\text{Price of jacket after discount}=100-(\frac{30}{100}*100)$

$\text{Price of jacket after discount}=100-30$

$\text{Price of jacket after discount}=70$

Therefore, price of jacket after discount is $70.

Now let us add both prices to find the total price of the items.

$\text{Total price of items}=30+70$

$\text{Total price of items}=100$

Therefore, the total price of the items bought by Sammy is $100.

B. To find the percent discount which Sammy got on his total purchases, we will use percent change formula.

$\text{Percent change}=\frac{\text{Difference}}{\text{Original value}}\times 100$

Total price without discount= 100+40=140

$\text{Discount percent}=\frac{140-100}{140}\times 100$

$\text{Discount percent}=\frac{40}{140}\times 100$

$\text{Discount percent}=0.2857142857142857\times 100$

$\text{Discount percent}=28.57142857142857\approx 29$

Therefore, Sammy got approximately 29% discount on his total purchases.
