A general equation to use for this situation is y = mx + b.
For this question, we can assume that y is total cost, m is cost per balloon, x is the amount of balloons, and b as the service fee; so we can set the equation up:
y = (4.50)x + 12
And we can further plug in the total cost to find the number of balloons purchased for the party:
79.50 = (4.50)x + 12
Now we can solve for x (number of balloons):
67.50 = (4.50)x
x = 15
The total number of balloons purchased for the party is 15.
The answer is 67 because 67 x 82 is 5,494 which us close to 5,514
Answer:
lol don't listen to him/her, they're wrong.
it's 0.92, for plato. i got it right
Step-by-step explanation:
If you would like to solve 5x - 65 = 3x - 17, you can do this using the following steps:
5x - 65 = 3x - 17
5x - 3x = 65 - 17
2x = 48
x = 48/2
x = 24
The correct result would be 24.
