If sara picks 4 flowers every minute, how many flowers will she have after half an hour if she had to throw away 3 flowers? what is the equation and the table ?

What exactly do you throw away 3 flowers? every 3 from the 4 she picked or 3 in total?

well i would say there is 30 minutes in half an hour and she picks 4 every minute, so that means you well have to multiply 30 x 4 = 120 - 4 = 116.
that would be equation.
