Answer: b. $22.75
Step-by-step explanation:
Given : A large pizza with no toppings costs $14.00. A large pizza with 2 toppings costs $17.50.
Let x denotes the number of toppings and y be the cost of that pizza.
Then,
, m= cost per topping and c= cost of pizza without any topping.
From the given information.
c= $14
Function of cost becomes = 
For x= 2 and y= 17.50, we have

tex]3.50=m(2)[/tex] [Subtract 14 from both sides]
[Divide both sides by 2]
For c= 14 and m =1.75 , our function becomes.

Now, for x= 5

Hence, the cost of a pizza with 5 toppings = $22.75
Answer:
The value of x is 20.
Step-by-step explanation:
Given that
Number of songs Marcus has = 10x+8
Number of songs Lara has = 15x-92
It is also given that they have the same number of songs that means both the expressions should be equal.
Putting both equal

This is a linear equation in one variable which can be solved using properties of equality
Subtracting 10 from both sides

Adding 92 on both sides

Dividing both sides by 5

Hence,
The value of x is 20.
