Answer:
20 ≤ y ≤ 70
Step-by-step explanation:
Range is the possible outout values
20 ≤ y ≤ 70
4 pencils . 4/9 of an hour = 4/9 of 60 minutes = 4/9 * 60 = 80/3 minutes
x pencils = ? . one hour = 60 minutes
14 * 60 = 80/3 * x /*3
14 * 60 * 3 = 80 * x
80 * x = 2520 /80
x = 2520 / 80
x = 31.5 pencils
The result would be 32 pencils in one hour.
(7/8)*(9/10)=7*9/(8*10)=63/80
