Answer:
Rate = 10%
Step-by-step explanation:
We are given with the following details.
Interest earned = $ 116.25
Principal = $ 1550
Interest Rate = r (say)
Time = 9 months
=
We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .
The formula for simple interest is given as
r=0.1
Hence the r = 0.1
Hence the rate of interest is 10%
Answer:
The selling price is $46 approx.
Step-by-step explanation:
The cost price is = $35.87
Markup is 22% of selling price.
Let the selling price be = 100%
So, 100%-22%=78% = 0.78
So, solution is = ≈ $46.
Hence, the selling price is $46 approx.

The midpoint of BC = D
x(mid) = (x(B) + x(C)) / 2 = (-2 + 4) / 2 = 1
y(mid) = (y(B) + y(C)) / 2 = ( 3 + 1) / 2 = 2
=> D(1,2)
Answer:
25
Step-by-step explanation:
y + ( - 16 ) = 9
y - 16 = 9
Add 16 on both sides,
y - 16 + 16 = 9 + 16
y = 25
