I would first like to know what they mean by y=kx and w=rt

kaylieanime · Answer

First you want to know how much time Jack can wrap 1 present and Luke as well. How about we start with Jack.
For every 3 presents Jack takes 15 minutes. Can you simplify?

kaylee04 · Answer

every 5 minutes he wrapped 1

kaylieanime · Answer

What about Luke?

kaylee04 · Answer

4 minutes for 1 present

kaylieanime · Answer

So if Jack's rate is 5 minutes per present and Luke's rate is 4 minutes per present, could you plug these into the functions (the y=kw or w=rt)?

kaylee04 · Answer

um 1=5 for jack and 1 = 4 for luke
