Answer:
Part a) 2 toppings
Part b)
Step-by-step explanation:
Part a) How many toppings need to be added to a large cheese pizza from Poppy's Pizzeria and Geo's Pizza in order for the pizzas to cost the same?
Let
x -----> the number of topping
y ----> the total cost of a large cheese pizza
we know that
<em>Poppy's Pizzeria</em>
----> equation A
<em>Geo's Pizza</em>
----> equation B
Equate equation A and equation B
Solve for x
Part b) What would that cost be?
we know that
For x=2 toppings the cost is the same in both pizzerias
so
substitute the value of x in equation A or equation B
<em>Poppy's Pizzeria</em>
Verify the cost in the other pizzeria (must be the same)
<em>Geo's Pizza</em>
----> is ok
