The <em><u>correct answer</u></em> is:
$43.20
Explanation:
The formula we have is
c = p(1+r), where c is the total cost, p is the price of the item before tax, and r is the tax rate written as a decimal. This formula comes from the fact that adding a percent tax to the cost of an item takes 100% of the price and adds r% to it; this is why we multiply the price by (1+r).
Since our tax rate is 8%, r = 8% = 8/100 = 0.08. The price of the item is $40. Using this information, we have:
c = 40(1.08) = $43.20
Step 1 is correct because it is easy method to do math equations
Well if it’s volume just multiply all the numbers together so 8x5= 40x3=120 so the answer would be 120
Answer:
The surface area of the composite figure is 
Step-by-step explanation:
we know that
The surface area of the composite figure is equal to the surface area of the rectangular prism of the bottom plus the lateral area o the rectangular prism of the top
so
Step 1
Find the surface area of the rectangular prism of the bottom
The surface area is equal to

Find the area of the base B



substitute

Step 2
Find the lateral area of the rectangular prism of the top
The lateral area is equal to



substitute

Step 3
Find the surface area of the composite figure
