Kelsie works at a concert arena. when the price of a ticket is $30, a concert will be attended by 2,500 people. each time the price is raised by an increment of $5, there will be 100 fewer people at the concert. kelsie uses the equation r=(30+5n)(2500−100n) to determine r, the total concert revenue in dollars when there have been n $5 increases in ticket price. which conclusion is valid?

the total concert revenue decreases when the price of a ticket is greater than $30.

the number of people attending the concert is represented by 2500−100n.

the number of times the price is raised is represented by 30+5n.

the cost per concert ticket must be less than $55.

step-by-step explanation:

answer: b

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

b. b < 1 might be the correct answer
