The break-even point is when there is no profit and no loss. Given the two equations for cost and revenue, we simply have to equate the two equations to solve for the unknown value, n. This is shown below:
C = 20n + 134000
R = 160n
R = C
160n = 20n + 134000
140n = 134000
n = 957.14
Among the choices, the nearest answer is D. 957.
Answer:
$7.80
Step-by-step explanation:
.40C-.20=T
C=# of chocolate bars
.20 is the coupon
C=20
.40*20-.20=Total
8-.20=Total
$7.80
The answer is digit sum method.
Digit sum method is method used to check the sum of sum numbers. If the sum of all of the digits of numbers is equal to the sum of all of the digits of the total sum, then the arithmetic process was correct.
We need to check the sum of <span>104+34+228+877:
</span>104 + 34 + 228 + 877 = 1243
Let's first summarize the digits of individual numbers:
104 *** 1 + 0 + 4 = 5
34 *** 3 + 4 = 7
228 *** 2 + 2 + 8 = 12 *** 1 + 2 = 3
877 *** 8 + 7 + 7 = 22 *** 2 + 2 = 4
Now, let's sum these sums:
5 + 7 + 3 + 4 = 19 *** 1 + 9 = 10 *** 1 + 0 = <u><em>1</em></u>
Then, let's summarize the digits of the total sum:
1243 *** 1 + 2 + 4 + 3 = 10 *** 1 + 0 = <u><em>1</em></u>
Since the sums of the digits on the both sides of equation is 1, than the arithmetic process was correct and the sum of <span>104 + 34 + 228 + 877 is really 1243.</span>
Answer:
- always start off with exponents.<em> a number</em>^2 means a number times itself.
- Next, multiply the previous number by 3.
- Now, add the product of the previous equation, and the sum of 3 times <em>x</em>.
- Next, find the value of 4 times <em>x</em>, and subtract it from the products of the previous two numbers.
- Now that we have the values of these 3 numbers, multiplied, added, and subtracted, add 5 onto the current value.
- Finally, subtract the value of all the previous numbers by 1.
Hope this helps in every way!
