You are hosting a convention for a charitable organization. you pay a rental fee of $28,500 for the convention center, plus you pay the caterer $13 for each person who attends the convention. suppose you just want to break even. how many must attend if you are to break even with a ticket price of $51?

750

Step-by-step explanation:

Given: You are hosting a convention for a charitable organization. You pay a rental fee of for the convention center, plus you pay the caterer for each person who attends the convention.

To Find: How many must attend if you are to break even with a ticket price of .

Solution:

Rent of convention center

Amount paid to caterer for each person

Cost of ticket of convention

Amount earned from each per person

To break even, the amount earned from all persons attending should be equal to rent

Let the number of persons be

Amount earned from all person

Total number of persons,  

Therefore 750 persons must attend the convention to break even with a ticket price of .

inch

step-by-step explanation:

yard and mile are too big.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
