To compute: the monthly cost of the cellular phone for use of the following number of anytime minutes.
(a)
Expert Solution
Answer to Problem 47AYU
C(200)=$39.99 .
Explanation of Solution
Given information:
Sprint PCS offers a monthly cellular phone plan for $39.99. It includes 450 anytime minutes and charges $0.45 per minute for additional minutes. The following function is used to compute the monthly cost for a subscriber:
C(x)={39.99 if0≤x≤4500.45x−162.51 ifx>450
Where x is the number of anytime minutes used.
Given number 200
Calculation:
When x=200 , the equation for cost C is C(x)=39.99 .
So,
C(200)=$39.99

Answer to Problem 47AYU
$46.74 .
Explanation of Solution
Given information:
Sprint PCS offers a monthly cellular phone plan for $39.99. It includes 450 anytime minutes and charges $0.45 per minute for additional minutes. The following function is used to compute the monthly cost for a subscriber:
C(x)={39.99 if0≤x≤4500.45x−162.51 ifx>450
Where x is the number of anytime minutes used.
Given number 465.
Calculation:
When x=465 , the equation for cost C is C(x)=0.45x−162.51 .
So,
C(465)=0.45×465−162.51=$46.74
