Answer:
B
Step-by-step explanation:
GIven that the lightest is 1.4 and the heaviest is 1.6, this implies that ALL the fruit must weigh between 1.4 and 1.6.
This also implies that the average weight of the fruit must also be between 1.4 lb and 1.6 lb.
recall that : average weight = total weight / number of fruit
we are given than total weight = 25.29 lb, so
average weight = 25.29 / number of fruit
Just go down the choices and test which choice gives an average weight between 1.4 and 1.6 lbs.
Choice A: number of fruit = 19
average = 25.29 / 19 = 1.33 (outside of range, not the answer)
Choice B: number of fruit = 17
average = 25.29 / 17 =1.49 (within range , possible answer)
Choice C: number of fruit = 10
average = 25.29 / 10 = 2.529 (outside of range, not the answer)
Choice D: number of fruit = 50
average = 25.29 / 50 = 0.5058 (outside of range, not the answer)
From the above, we can see that only B gives an average between 1.4 and 1.6 lb.
