Answer:
Minutes to make one balloon sculpture = 5 minutes
Balloons are used for one balloon sculpture= 8 balloons
Tomas use balloons = 1.6 per minute
Step-by-step explanation:
a).
180 minutes = 36 sculpture
![\frac{180 }{36 } = 5](https://tex.z-dn.net/?f=%5Cfrac%7B180%20%7D%7B36%20%7D%20%3D%205)
5 minutes to make a sculpture
b).
288 balloons = 36 sculpture
![\frac{288 }{36 } = 8](https://tex.z-dn.net/?f=%5Cfrac%7B288%20%7D%7B36%20%7D%20%3D%208)
8 Balloons to make a sculpture
c).
288 Balloons = 180 minutes
![\frac{288}{180} = 1.6](https://tex.z-dn.net/?f=%5Cfrac%7B288%7D%7B180%7D%20%3D%201.6%20)
1.6 Balloons per minute
The second graph is correct
Let's use the variable n for time (in hours)
70n + 80n = 270
150n = 270
n = 1.8
It will take 1.8 hours, or 1 hour and 48 minutes
