A puppet show crew uses a timer that includes both negative and positive minutes for before and during the play. If it takes the crew 40 minutes to assemble the box stage, 13 minutes to organize the sock puppets, and 10 minutes to greet the children, what time should the timer read when they begin?
–63 minutes
–17 minutes
0 minutes
53 minutes
Because you adding all the time together, and if they mean by "start" including greeting the chidren, then it would be 53 minutes. But I'm pretty sure its A.
