Mrs travis wants to have the clown deliver balloons to her secretary's office. clowns r fun charges $1.25 per balloon and $6 for delivery. singing balloons charges $1.95 per gallon and $2 for delivery. what is the minimum number of balloons mrs. travis needs to purchase in order for clowns r fun to have a lower price than singing 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.

There is no question, there is just the answer.
