We are supposed to explain why the given function can be expressed in form
, when
.
Since the given function is an exponential function we can express it as
.
Now let us substitute x=0 in the given function,

Let us substitute x=0 in our function.
Upon substituting a=1 in our function we will get,

Therefore, our function f can be represented by the formula of the form
.
Your expected value is 36*2/6 + -36*4/6, which is equal to $-12.
58300 - 8300 - 12750 - 22400 = 14850
We take the total profit (58300) and subtract the value of all 3 contracts to see what is left over. That remaining amount (14850) is the final contract.
Answer:
x = -3; y = 2
Step-by-step explanation:
5x + 2y + 19 = 0
3x + 4y + 17 = 0
-10x - 4y - 38 = 0
3x + 4y + 17 = 0
-7x - 21 = 0
x = -3
5(-3) + 2y = -19
2y = -4
y = -2
Answer: x = -3; y = 2
⇒The answer to the first question would be $69.75.
⇒The answer to the 2nd question would be $36.48.
⇒The answer to the 3rd question would be $42.7.
Here's how to get them:
For question 1: A 55% markup for $45 ⇒1.55*45⇒69.75
For question 2: A 60% markup for $22.8⇒ 1.6*22.8⇒36.48
For question 3: A 40% markup for $30.50⇒1.4*30.50⇒42.7
Small Explanation: The reason why there should be a 1 in front of the decimal (which is the percent, but in decimal form) is because by not adding that number 1 in front of the decimal, you will have to do an extra step.
Anyway, hope this helped! :-)
