Question

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?

Answer 1

Answer:

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
