Answer:
As many as 7 apples or as few as 4 apples could be green.
Step-by-step explanation:
Laura picks 7 apples.Some apples are red and some are green. Fewer than 4 of the apples are red. How many of laura's apples could be green?
x = total number of red apples
y = total number of green apples
Fewer than 4 of the apples are red.
x<4
That means that 3 or less of the apples are red
So, 7 - 3 = 4
That means that 4 or more apples are green.
7≥y≥4
That means that as many as 7 apples or as few as 4 apples could be green.
