Answer:
Month 5 is when it will be at $100
I hope this helps!
Step-by-step explanation:
x---0-----1-----2-----3----4-----5
y-300-260-220-180-140-100
y=40x+300
Here are some Examples: :)

is 0.2222222222 and so on

is 0.4444444444 and so on

is 0.777777777 and so on
So it could be anything like 9 or 6 as long is its like this

10 = 2x5
4 = 2x2
LCM + 2x2x5 = 20 <=== smallest number of bracelets and hair bow to buy
The perimeter because the fence goes AROUND the yard, not in it.
P = 2w + 2l
P = 2(60) + 2(20)
P = 120 + 40
P = 160
