Answer:
Option C. $30
Step-by-step explanation:
As per question buyers are willing to pay $135 per tuning. If David demands more than this amount producer will not choose David to tune.
As we can see on first week David is willing to tune the first piano for $115,
So surplus for producer will be
135 - 115 = $20
Surplus for second week for producer will be
135 - 125 = $10
Since David is willing to tune the third and fourth piano for $140 and $175 then the producer will not choose David for tuning.
Therefore, total surplus for the producer will be $20 + $10 = $30
Option C. $30 is the correct option.
Answer:
8
Step-by-step explanation:
Since we are adding small numbers we can use our hands to solve it.
1) We can use one hand to represent the value of 5
2)We use the other hand and lift tree fingers up.
3)counting the fingers will give you a total of 8
Answer:
-2/7
Step-by-step explanation:
2x+7y=14
7y=-2x+14
divide by 7
y=-2/7 x+2
The answer is D because a function means for every input you get exactly one output so
for every x you get one y
in D there is a coordinate (5,2) meaning that if you put in 5 for x you get 2 for y
but the new ordered pair also has 5 for x but has a difarent y value. this violates the definition of a funciton
The tip would be 22.5 and to check multiply 150 by .15 which equals 15%
