Question:
Tomas makes balloon sculptures at a circus.in 180 minutes,he uses 252 balloons to make 36 identical balloon sculptures.
b. what is tomas's unit rate for balloons used per minute.
Answer:
Tomas unit rate for ballons used per minute is 1.4 ballons per minute
Solution:
Given that in 180 minutes, tomas uses 252 ballons to make 36 identical sculptures
To find number of minutes to make 1 sculpture divide 180 by 36
[tex]\text { number of minutes to make 1 sculpture }=\frac{180}{36}=5[/tex]
So he takes 5 minutes to make 1 sculpture
Given that he uses 252 ballons to make 36 sculptures
To find number of ballons in 1 sculpture divide 252 by 36
[tex]\text { number of ballons in 1 sculpture }=\frac{252}{36}=7[/tex]
So he uses 7 ballons in 5 minutes
To find unit rate for ballons used per minute divide 7 by 5
[tex]\text { unit rate for ballons used per minute }=\frac{7}{5}=1.4 \text { ballons per minute }[/tex]
Thus tomas unit rate for ballons used per minute is 1.4 ballons per minute
