Is there a problem equation?
So the pay after the increase is 4380 so subtract 4380-584 which equals 3796.
Answer:
it's B I think because I worked it out and I got B
Area of square = atleast 36 = length *width, where l = w (since it's a square)
If A=36, l = w = 6
If A = 37, l = w = 6.08
if A =38, l = w = 6.16
So the solution set is s => 6 (s is bigger than or equal to 6)
