7/5 - 10/5 = -3/5
I hope this helps.
Answer: 896
Step-by-step explanation:
Let's use a rule of three here.
Solve for x;
You can do:
16 - 10 and then + 1 (thats 7)
9+ ? is 16 ? ( 7)
The answer is (1,-4)
Remember that the vertex is the center of the parabola.
At Gino's you pay $16 plus $8 per pizza.
At Venetian's you pay $24 plus $6 per pizza.
Let the number of pizzas be x.
At Gino's you pay 16 + 8x
At Venetian's you pay 24 + 6x
Set the two costs equal and solve for x to find out the number of pizzas for which both costs are the same.
16 + 8x = 24 + 6x
16 + 2x = 24
2x = 8
x = 4
Each place gives you a free pizza.
4 pizzas plus the free pizza equals 5 pizzas.
If you need 5 pizzas (including the free one), both parlors cost the same.
If you need fewer than 5 pizzas, use Gino's.
If you need more than 5 pizzas, use Venetian's.
