One location of the smart growing preschool has 22 children in the primary class and 18 children in the toddler class. the other location has 30 children in the primary class and 15 children in the toddler class. the revenue at the first location is $24,250, and the revenue at the second location is $27,150. how much do parents pay for a primary child and a toddler child every month?

Parents pay $595 for a primary child and $620 for a toddler child every month.

Step-by-step explanation:

Let x be the monthly fee of a primary child and y be the monthly fee of a toddler child.

The Smart Growing Preschool has 22 children in the primary class and 18 children in the toddler class. The revenue form Smart Growing Preschool is $24,250.

                .... (1)

The other location has 30 children in the primary class and 15 children in the toddler class. The revenue at this location is $27,150.

                .... (2)

On solving (1) and (2) by graphing calculator, we get

Therefore parents pay $595 for a primary child and $620 for a toddler child every month.

step-by-step explanation:

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
