Question 322698: Paula broke half as many balloons as Perry. Altogether they broke 18 balloons. How many balloons did perry break? Answer by jessica43(140) (Show Source):
You can put this solution on YOUR website! To solve this problem you need to write two equations based on what you know.
First, you know that Paula broke half as many balloons as Perry:
A = (1/2)E (A = number of balloons Paula broke, E= number of balloons Perry broke)
Second, you know that together they broke 18 balloons:
A + E = 18
Now you can plug in the first equation into the second and solve for E:
A + E = 18
(1/2)E + E = 18
(3/2)E = 18
E = 12
So Perry broke 12 balloons and Paula broke 6.
