Answer:
In the Garden Club the cost will be a fixed fee of $25 and $10 for each rosebush, so if he buys X rosebushes, the total cost will be:
C1(X) = $25 + $10*X
While in the local nursery there is no initial cost, and each rosebush costs $15, so if he buys X rosebushes, the total cost will be:
C2(X) = $15*X
Now, let's find the value of X where C1 and C2 are equal, this is:
$25 + $10*X = $15*X
$25 = $15*X - $10*X = $5*X
X = 25/5 = 5
This means that if he buys 5 rosebushes, he will pay the same amount in both places.
If he buys less than 5 rosebushes, he will pay less in the local nursery (as it has a bigger slope, but no initial fee)
If he buys more than 5 rosebushes, he will pay less in the Garden club (because it has a smaller slope)
You can work out the percentage change and that would help you work out the rate of appreciation :)
The formula is ((new value - old value)/old value) * 100.
So you do 
Therefore the rate of appreciation is 8% p/a.
A= 2.5
b= 2
LM/ON= 15
LO/MN= 5
Answer:
A
Step-by-step explanation:
mid point of AC=((2m+2p)/2,(2n+2r)/2)=(m+p,n+r)
Answer:
x = 10
Step-by-step explanation:
Since L is the midpoint
KL = LM
2x-3 = x+7
Subtract x from each side
2x-3-x = x+7-x
x-3 = 7
Add 3 to each side
x-3+3 = 7+3
x = 10
