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.

Answer:
22 bundles of shingles are required to cover the roof.
Step-by-step explanation:
A square pyramid roof has five total sides. A square base and 4 equilateral triangle. The 4 triangular sides are to be covered by shingles.
Given:
The gutter to top = height = 15 ft
The length of the gutter on one side = length of roof base = 18 ft
Area covered by one bundle of shingles = 25 square feet.
Bundles to be bought = x = ?
Area to be covered by shingles = 4*Area of one side
= 4*((height*length)/2)
= 4*((15*18)/2)
= 4*135
= 540 square feet
Now x = Area/ area covered by one bundle
x = 540/25
x = 21.6
x = 22 bundles
