Answer:
1. 13x/760-13x
2. X = 29.23
3. X> 29.23
4. X<29.23
5. Max price = 29.23c
Step-by-step explanation:
1. D(x) = 760-13x
To get Elasticity, we differentiate the equation
D'x = -13
Elasticity is expressed as:
E(x) = -x*D'(x)/760-13x
= X(-13)/760-13x
B. Price elasticity with demand = 1
13x/760-13x = 1
We cross multiply
13x = 1(760-13x)
13x = 760-13x
Collect like terms
26x = 760
X = 29.23
C. When elasticity of demand is elastic
13x/760-13x > 1
We cross multiply
13x > 1(760-13x)
13x > 760-13x
Collect like terms
26x > 760
X > 29.23
C. Greater than 29.23
D. When inelastic
This follows same solution as 2 and 3 but the sign is different.
E(x) <1
13x/760-13x < 1
We cross multiply
13x < 1(760-13x)
13x < 760-13x
Collect like terms
26x < 760
X < 29.23
B. less than 29.23
E. We get total revenue
X(760-13X)
= 760x - 13x²
We differentiate this
760-26x = 0
760 = 26x
X = 29.23
revenue is a maximum at price is 29.23c
f. The last question is incomplete
Well... that's to hard for me sadly when I learned a lot how to do that, i'll give you this though when you going from bigger to smaller you divide, when you going smaller to bigger you times.
Good luck though ;)
Step-by-step explanation:
If the contents of one cup are split up into 3 equal parts, each will be one third of the cup. Each cup has three thirds, Therefore in 6 cups there will be six times as many thirds. We can also calculate by dividing.
I hope it's helpful!
A I’m pretty sure that’s the answer
The equation for the total amount charged is y = 60 + 45x
<h3>How to create the equation?</h3>
The given parameters are:
Rate = $60 per service
Installation = $45
Let y represents the total charges and x represents the number of services.
So, we have
y = Installation + Rate * x
This gives
y = 60 + 45 * x
y = 60 + 45x
See attachment for the graph of the function
