Some years ago it was estimated that the demand for steel approximately satisfied the equation p = 356-30x, and the total cost of producing x nits of steel was y -100 + 6x he quantity x was measured in mi ons of tons and the price and total cost were measured in millions of dollars determine the level of production and the corresponding price that maximize the profits thj maximum profit occurs at x·? (million tons) the corresponding price is ? dollars per ton

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

c

step-by-step explanation: easy math

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
