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.
Therefore, price of shoes after discount is $30.
Now let us find price of jacket after 30% discount.
Therefore, price of jacket after discount is $70.
Now let us add both prices to find the total price of the items.
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.
Total price without discount= 100+40=140
Therefore, Sammy got approximately 29% discount on his total purchases.
