The graph models the cost of a cheese pizza with extra toppings at two different restaurants. according to the graph, about how many pizza toppings will need to be added to make the cost of the pizzas equal? a) 4 b) 8 c) 12 d) 14 pls answer

Let's begin by assigning a letter to represent our unknown:     x = # of toppings to be added to each pizza   Now let's come up with expressions for the cost of each pizza with its toppings:     Palanxio's Pizza:  6.80 + 0.90x     Guido's Pizza:  7.30 + 0.65x   Now let's equate the costs of both pizzas and solve for our unknown (x):     6.80 + 0.90x = 7.30 + 0.65x     0.90x - 0.65x = 7.30 - 6.80     0.25x = 0.50     x = 0.50/0.25     x = 2 toppings to be added to each pizza   Finally, we can verify our answer by plugging it back into our equation and see if both costs are the same:     6.80 + 0.90x = 7.30 + 0.65x       [equation]     6.80 + 0.90(2) = 7.30 + 0.65(2)  [answer plug-in]     6.80 + 1.80 = 7.30 + 1.30     $8.60 = $8.60  [both costs are the same]   Since both costs are the same, we are confident that our answer is correct.  

Idon’t feel like doing the math but you need to do 2.24 divided by 7
