I have to assume that someone goes into the store and buys 3 pens for $1.50, 8 for $4 and 12 for $6.  This is a bit confusing until you verify that the unit cost per pen is the same in all three cases.

3 pens for $1.50 comes out to $0.50 per pen;
8 pens for $4 comes out to $0.50 per pen; and 
12 pens for $6 comes out to $0.50 per pen.

Summarizing:  c = ($0.50)p

1/2d + 6 = 1/2 (d + 3)

Hope this helps!

A pizza parlor offers 3 sizes of pizzas, 2 types of crust, and one of 4 different toppings. How many different pizzas can be mad
KonstantinChe [14]

Answer:  The total number of  pizzas that can be made from the given choices is 24.

Step-by-step explanation:  Given that a pizza parlor offers 3 sizes of pizzas, 2 types of crust, and one of 4 different toppings.

We are to find the number of different pizzas that can be made from the given choices.

We have the <em><u>COUNTING PRINCIPLE :</u></em>

If we have m ways of doing one task and n ways of doing the second task, then the number of ways in which we can do both the tasks together is m×n.

Therefore, the number of different pizzas that can be made from the given choices is

N=3\times2\times4=24.

Thus, the total number of  pizzas that can be made from the given choices is 24.
