Unformatted text preview: Chap ter 10 Marys Deli sells a large cheese pizza for $9.00 Questions: How much would a large pizza with 5 toppings cost? If you paid $12.75 for a large pizza, how many toppings did you order? Each additional topping costs $1.25. # of Toppings 1 2 3 4 5 6 Total Cost ($) 9.00 10.25 11.50 12.75 14.00 15.25 16.50 Complete the chart to determine the cost for each number of toppings. Create a graph that describes the data. Let the horizontal axis represent the number of toppings Let the vertical axis represent the total cost # of Toppings 1 2 3 4 5 6 Total Cost ($) 9.00 10.25 11.50 12.75 14.00 15.25 16.50 Cost of a Large Pizza at Mary's Deli 5 10 15 20 1 2 3 4 5 6 # of Toppings Total Cost ($) Notice: the difference between the total cost for consecutive toppings is constant (cost of topping t ) (cost of topping t 1 ) 10.25 9.00 = 1.25 11.50 10.25 = 1.25 12.75 11.50 = 1.25 14.00 12.75 = 1.25 15.25 14.00 = 1.25 16.50 15.25 = 1.25 1.25 is called the COMMON DIFFERENCE The book uses d to represent the common difference When the differences between consecutive values in a sequence are the same, a LINEAR GROWTH MODEL can be used to describe the growth.
