We need to find the unit rate, which is how many per hour.
If he can make 1 in 30 minutes, he can make 2 in an hr.
We can now set up an equation with y=2x where y is the number of masterpieces and x is the number of hours. Plug in the values into y and calculate.
y=2(2)= 4
y= 2(10)= 20
y= 2(24)= 48
Final answers: 4 masterpieces; 20 masterpieces; 48 masterpieces
