Question

In order to join a voice lesson class, you pay a ₱1,500.00 pesos fee, then ₱500.00 for

each class you go to. What is the average cost per class? Graph the function to show

whether it forms a straight line or a curve.​

Answer 1

Answer:

Step-by-step explanation:

pesos fee = 1500

each class fee = 500

no of class = xx

average fees(A) per class = \frac{1500+500x}{x}

x

1500+500x

​

if xx = 1

average fees = \frac{1500+500(1)}{1}

1

1500+500(1)

​

= 2000

if xx = 2

average fees = \frac{1500+500(2)}{2}

2

1500+500(2)

​

= 1250

if xx = 3

average fees = \frac{1500+500(3)}{3}

3

1500+500(3)

​

= 1000

if x = 4

average fees =\frac{1500+500(4)}{4}

4

1500+500(4)

​

= 875

now we got number of classes and average fess , now we plot the graph between these points

x= number of classes and A = average fees

x = 1 , A = 2000

x = 2 , A = 1250

x = 3 , A = 1000

x= 4 , A = 875
