A pizza shop sells a large pizza with 8 slices for $8.50. They sell a small pizza with 4 slices for $4.50. What is the unit rate(price) of each pizza? Which is the better deal?

Large Pizza: $1.06

Small Pizza: $1.13

Large Pizza is the better deal.

Step-by-step explanation:

We need to set up two equations for each scenerio. One for the large pizza and one for the small pieces.

We know that a pizza shop sells 8 large slices and costs $8.50.

We also know that they also sell 4 small slices and costs $4.50.

But, we don't know how much each of these will cost. So, we need to add a variable by x that will equal the cost of the pizza.

Our equations:

8x = 8.50

4x = 4.50

Now solve for each equation:

Large pizza:

Small pizza:

Now, we know how much each pizza slice cost for both small pizza and large pizzas.

A slice from a large pizza costs: $1.0625 or $1.06.

A slice from a small pizza costs: $1.125 or $1.13

It seems like the better deal is the large pizza since the cost per slice is lower than the small pizza's slice per cost.

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf = 

pf = 6,25 u
