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:
3.5°
Step-by-step explanation:
Subtract 82 and 54, to find the total change in temperature, 28.
7:00 am and 3:00 pm are 8 hours apart, so divide 28 by 8.
Your answer should be D, 3.5° per hour.
The only ones that would work are if the factor is composite and if 1 is added to it it can be divided into 48. So 15 would work. The factor 15 is composite, and if 1 is added it can be divided into 48.Therefore the son is 15.
As given,
The diameter of one glass bead = 0.4 cm
As the beads are stringed/attached end to end that means a straight line of beads (diameter) can be imagined and adding up all the diameters or multiplying the diameter with total number of beads, we can get the total length of the necklace.
Hence, the length can be found as =
cm
or converting this in meters we get 
meter
Hence, the necklace will me 40 meters long.
