The profit would be the difference between the total amount earned after selling each and every shirt and the costs of buying them so
p(x)= r(x)- c(x)
7x-20?
They will each get 1/6 of the pizza.
From the table we can see:
Number of songs: Cost:
0 $ 0
1 $1.25
2 $2.50
3 $3.75
4 $5.00
Therefore the rate of change is: (2.50 - 1.25) / ( 2 - 1 ) = $1.25
Answer:
It means that : C. The cost increases $1.25 for each additional song that is downloaded.
Elga's age = x
Alvin's age = x + 7
x + x + 7 = 97.
Simplify the left side of the equation
2x + 7 = 97.
Subtract 7 from each side
2x = 90.
Divide each side by 2
x = 45
Since x is equal to Elga's age, Elga is 45 years old
Its A, all y-values are less than -3x+5. also consider root by setting -3x+5=0
x=5/3 is positive so its the first one
