The <em>correct answer</em> is:


6 balloons.


Explanation:


Let x represent the number of balloons purchased.


We will call the function for Clowns R Fun c(x):

c(x) = 1.25x+6


We will call the function for Singing Balloons s(x):

s(x) = 1.95x+2


We want the amount for Clowns R Fun, c(x) to be less:

c(x) < s(x)

1.25x+6 < 1.95x+2


Subtract 1.25x from each side:

1.25x+6-1.25x < 1.95x+2-1.25x

6 < 0.7x+2


Subtract 2 from each side:

6-2 < 0.7x+2-2

4 < 0.7x


Divide each side by 0.7:

4/0.7 < 0.7x/0.7

5.7 < x

x > 5.7


She must buy more than 5.7 balloons; the next integer up is 6. She must buy 6 or more balloons.

Given:
Clowns R fun = 1.25 per balloon + 6 for delivery
Singing Balloons = 1.95 per balloon + 2 for deliver

1.25x + 6 = 1.95x + 2
1.25x - 1.95x = 2 - 6
-0.7x = -4
x = -4 / - 0.7
x = 5.71 or 6 balloons

Clowns R Fun = 1.25*6 + 6 = 7.5 + 6 = 13.5
Singing Balloons = 1.95*6 + 2 = 11.7 + 2 = 13.7  
If x is 6 = ALMOST THE SAME

Clowns R Fun = 1.25*5 + 6  = 6.25 + 6 = 12.25
Singing Balloons = 1.95*5 + 2 = 9.75 + 2 = 11.75
If x is 5 = Singing Balloons is cheaper

Clowns R Fun = 1.25*7 + 6 = 8.75 + 6 = 14.75
singing Balloons = 1.95*7 + 2 = 13.65 + 2 = 15.65 
If x is 7 = Clowns R Fun is cheaper

Mrs. Travis needs to order a minimum of 7 balloons in order for Clowns R Fun to have a lower price than Singing Balloons.

When you are determining The probability of an event why must the probability be between 0 and 1
slega [8]

The probability of an event cannot be less than 0 because 0 means it's impossible. The probability of an event cannot be more than 1 because 1 means that it's certain that it will happen. That's why the probability must be between 0 and 1.
