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.
Tomas unit rate for ballons used per minute is 1.4 ballons per minute
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
