El ingreso mensual por concepto de la venta de x unidades de cierto artículo está dado por I(x) = -0.01x² + 12x dólares. Determine el número de unidades que deben venderse cada mes con el propósito de maximizar el ingreso.

¿Cuál es el correspondiente ingreso máximo?

¿Cuando el ingreso será cero?

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

i need more details sorry

step-by-step explanation:

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
