Question

susan took 2 hours to write 30 party invitations write an equation to represent the number of minutes m susan spend writing x invitations

Answer 1

In order to solve for the variable m, first, you have to convert 2 hours to 120 minutes then you have to have the rate of invitations per minute (x/m). Once you have the rate (0.25) you get this formula m=x/0.25. which if you plug the x variables into you will find is correct.
