Answer:
D.
Step-by-step explanation:
the graph,, top of the graph says year and students enrolled
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.

Answer: A) The product is rational</h3>
Explanation:
The number 4.56 is rational because any terminating decimal can be written as a fraction of two integers. For example, 4.56 = 456/100
The number is the same as where the '5's go on forever. Repeating decimals like this are rational. It turns out that which you can find through trial and error, or apply a bit of algebra. I'll skip showing those steps unless you need me to go over them.
Because both given numbers are rational, multiplying those two rational numbers will lead to another rational number
rational times rational = rational
I'll skip over the proof of this as well unless you need me to show it.
