Sagot :

Answer:

(a) The initial value is 40

(b) 510 Euros

Step-by-step explanation:

Given

[tex]M = 5x + 40[/tex]

Solving (a): The initial charge

A linear function is represented as:

[tex]y=mx + c[/tex]

Where c is the initial value

By comparison:

[tex]c = 40[/tex]

Hence: The initial value is 40

Solving (b): Amount charged for 94

Substitute 94 for x in [tex]M = 5x + 40[/tex]

[tex]M = 5 * 94 + 40[/tex]

[tex]M = 510[/tex]

510 euros for 94 orders
