¡Ventas Un vendedor de bebidas gaseosas en una conocida playa analiza sus registros de ventas y encuentra que si vende x
latas de gaseosa en un día, su utilidad (en dólares) está dada por
P(x) = -0.001x? + 3x
- 1800
•Cuál es su utilidad máxima por día, y cuántas latas debe ven-
der para obtener una utilidad máxima?

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

3+3+3+2*2*2+29*12 = 365
