Answer:
Sarah can iron 8 shirts in 12 minutes
If t=1 hour, s=40
Step-by-step explanation:
Sarah irons at a constant rate.
She can iron no. of small t-shirts in 18 minutes = 12
She can iron no. of small t-shirts in 1 minute =[tex]\frac{12}{18}=\frac{2}{3}[/tex]
Rate = [tex]\frac{2}{3}[/tex]
General equation : y=mx
Where m is the slope
Slope = rate of change
Substitute the rate in equation
So, [tex]y =\frac{2}{3} x[/tex]
[tex]s=\frac{2}{3} t[/tex]
where t represents the minutes
t represents the no. of t shirts
Now we are supposed to find How many shirts could Sarah iron in 12 minutes
Substitute t = 12
[tex]s =\frac{2}{3} (12)=8[/tex]
Sarah can iron 8 shirts in 12 minutes
If t=1 hour, s= ______.
1 hour = 60 minutes
[tex]s =\frac{2}{3} (60)=40[/tex]
So,If t=1 hour, s=40
