So, what is the case in which he uses the least coins? can he use 1 coin? no, there isn't a 35 cent coin. can he use 2 coins? yes! he can use 25+10 cent coins!
now, the largest number of coins means the coins of the smallest value: so using only 5 cent coins. How many would this be?
we have to divide:
35/5=7
so we would use 7 coins.
And the difference is 5: 7-2 is 5.
The slope or distance is 4/-3
Answer:
The function that represents the average cost in dollars of saleable software CD is given as follows;
f(x) = 500,020/x + 0.10
Step-by-step explanation:
The given parameters are;
The cost of manufacture of each software CD = $0.10
The development cost to produce the CD = $500,000
The number of CDs that are not sold = The first 200 CDs
The total cost of production. 'C', of the the CD is given as follows;
C = $500,000 + $0.10×200 = $500,020
The function, 'f' for the average cost in dollars of a saleable software CD where 'x' is the number of saleable software CDs is given as follows;
f(x) = (C + 0.10·x)/x = C/x + 0.10
∴ f(x) = 500,020/x + 0.10.
C. Only one pair of sides is parallel.
