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.
<h2>Answer:</h2>
Graph C
<h2>Step-by-step explanation:</h2>This is a piecewise-defined function because it is defined by two equations over a specified domain and this domain is . The first function comes from the pattern of the square root function
and the second one is a linear function.
The graph of has been shifted one unit to the left of
and stretched vertically where each y-value is multiplied by 3.
Moreover, we can prove that:
The graph of passes through points (0,3) and (3,6):
It passes through these points.
The graph of passes through points (5,0) and (3,2):
It passes through these points.
