2. Use the information in the table to find the cost of a pizza with 6 toppings. number of toppings
cost of pizza
2
$11.99
3
$13.49
4
$14.99
5
$16.49
6
3. Is there a proportional relationship between the number of toppings on a pizza and its cost? Explain in a
complete sentence using your work from above

The proportional relationship is + 1.50 with each toppings. The cost for 6 toppings is $17.99.

Step-by-step explanation:

11.99 to 13.49 is + 1.50, 13.49 to 14.99 is + 1.50, and so on.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
