Un empresario compró 1000 tabletas a $1500 cada una. Vendió 450 de ellas obteniendo una ganancia del 25%.
¿ A qué precio deberá vender las otras 550 restantes si la utilidad promedio del lote completodebe ser del 40%?

Step-by-step explanation:

1000($1500(0.40)) = $600 000

450($1500(0.25)) = $168,750

600,000 - 168,750 = $431,250

$431,250 / 550 = 784.0909090... $784.09

$1500 + $784.09 = $2,284.09

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
