Answer 2

Answer:

for que-5

Correct answer:

f(x)=0.75(x−1)+5

Explanation:

Notice that the question describes a linear equation because there is a constant rate of change (the cost per topping). This means we can use slope intercept form to describe the scenario.

Recall that slope intercept form is

y=mx+b

The value of b is the y-value when x=0. In this case x=0 means there are zero additional toppings and the question tells us that this pizza costs $5 so:

5=m(0)+b

5=b

m is the slope, or rate of change as x increases. In this case each additional topping costs 75 cents. Notice that the units have shifted from dollars to cents so we must write this as 0.75

m=0.75

Notice that the first topping is included in the $5 cost. The 75 cent charge only applies to additional toppings. So one less than the number of toppings is equivalent to:

x−1

Putting all these steps together we get:

0.75(x−1)+5
