Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft
Answer: £5
Step-by-step explanation:
Bole sold the article for 125% while he bought it for 100%.
Bole sold for £7.50 so £7.50=125%
£7.50/1.25=£6
125%/1.25=100%
£6=100% (the cost Bole bought the article with from Iluguru)
Iluguru sold it at 120% so 120% is £6
To find 100% we divide by 1.2
£6/1.2=£5
Iluguru bought article for £5 originally
