Step-by-step explanation:

The complete question in the attached figure

Part a) Two large cheese pizzas and three large pepperoni pizzas are

ordered. Write and simplify an expression that represents the

total cost total cost

we know that

The total cost is equal to the cost of two large cheese pizzas plus the cost of three large pepperoni pizzas

step 1

The cost of two large cheese pizzas is

step 2

The cost of three large pepperoni pizzas is

----> looking at the table for one topping

therefore

The total cost is

Part b) Write and simplify an expression that represents the total cost of

eight large pizzas, if two are cheese and six have four toppings

each.

we know that

The total cost is equal to the cost of two large cheese pizzas plus the cost of six large pizzas with four toppings

step 1

The cost of two large cheese pizzas is

step 2

The cost of six large pizzas with four toppings is

----> looking at the table for four toppings

therefore

The total cost is

Part c) Elsa orders three large cheese pizzas, a large pepperoni and

mushroom pizza, and a large green pepper and onion pizza.

Write and simplify an expression that represents the total cost

we know that

The total cost is equal to the cost of three large cheese pizzas plus the cost of two large pizzas with two toppings  each

step 1

The cost of three large cheese pizzas is

step 2

The cost of two large pizzas with two toppings  each is

----> looking at the table for two toppings

therefore

The total cost is

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
