Answer:
$20196
Step-by-step explanation:
12 × 9 × 6 = 648 cubic feet ( volume of slab )
3 feet to a yard
So 648 ÷ 3 = 216
Multiply this by 1.1 to add an extra 10%
237.6 Cubic Yards Needed
$85 × 237.6 = $ 20196
Hope this helps
Answer:
Step-by-step explanation:
To verify, a number needs to be substituted for x in both expressions. Use order of operations to simplify and find the value. The value needs to be the same for both expressions to prove
Over time, compound interest at any rate will outperform simple interest. When the rates are nearly equal to start with, compound interest will be greater in very short order. Here, it takes less than 1 year for compound interest to give a larger account balance.
In 30 years, the simple interest will be
... I = P·r·t = 12,000·0.07·30 = 25,200
In 30 years, the compound interest will be
... I = P·(e^(rt) -1) = 12,000·(e^(.068·30) -1) ≈ 80,287.31
_____
6.8% compounded continuously results in more total interest
After selling 35 books, the store will break-even.
Step-by-step explanation:
Given,
Cost required per day to keep store open = $105
Amount spent on each book = $12
Let,
n be the number of books.
Total costs = 12n + 105
Selling price of each book = $15
Total revenue = 15n
For braking even;
Costs = Revenue

Dividing both sides by 3

After selling 35 books, the store will break-even.

Let price of the Caleb's groceries was $x.
Given that tax rate is 2.5% or 0.025
Then sales tax is given by product of 0.025 and x.
which is 0.025x.
Given that tax paid is $1.60 so both must be equal

divide both side by 0.025


Hence final answer is $64.
