Marjorie baked 100 cupcakes for a bake sale. she sold each cupcake for $0.50. the function p(c) = 0.50c represents the amount, in dollars, that she earned from the bake sale by selling c cupcakes. what domain and range are reasonable for the function?

The answer in the procedure

Step-by-step explanation:

we have

P(c)=0.50c

where

P(c) ---> is the amount in dollars that Marjorie earned from the bake sale

c > is the number of cupcakes

The domain of the function are the number of cupcakes sold

so

The domain is the interval > [0,100]

All positive integers greater than or equal to 0 and less than or equal to 100

Find the range

For c=0

P(0)=0.50(0)=$0

For c=100

P(0)=0.50(100)=$50

The range is the interval > [0,50]

All real numbers multiples of 0.50 greater than or equal to 0 and less than or equal to 50

it would more likely be bald eagle because its has more in the box so about 75%.

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
