Lewis and Paula both work at a fast food restaurant. When they both work together building sandwiches, they can make 70 sandwiches in one hour. Alone, Lewis can build 25 sandwiches in 45min. How many sandwiches does Paula build every hour working alone?
Together DATA:: rate = 70 s/h
Lewis DATA:: rate = 25 s/(3/4)h = 100 s/3h = 33 1/3 s/h
Paula DATA:: rate = x s/h
----------
Equation::
rate + rate = together rate
x + 33 1/3 = 70
x = 36 2/3 s/h (# of sandwiches Paula builds in an hour)
