(minutes) Scientist Number of Leaf
Samples Tested Time Spent
(minutes)
Steve 90 30 Mary 140 35
Jesmy 180 45 Brian 160 40
Buck 210 60 Kate 220 55

Which laboratory shows a proportional relationship between the number of leaf samples tested and the time spent testing

not me

don’t know last one sorry

step-by-step explanation:

i hope that is right.

step-by-step explanation:
