Answer:
K+T=20
$9K + $6T = $168
K is the Kentucky blue grass in pounds
T is the Tall fescue in pounds
Step-by-step explanation:
You can start with the first equation. We don't know the exact amounts of each but we know that there was a total of 20 pounds, and there were 2 types of grass seeds, so we can get that the amount of pounds of Kentucky blue grass(K) and the pounds of Tal Fescue(T) has a sum of 20.
K + T = 20
For the second equation we know that there is a sum of $168 so we'll start with that. Then, we know he paid $9 per pound of K so $9* the value of K is the amount paid for Kentucky blue grass total. This can be represented as 9K. We do the same for T, 6T. Since the sum of the cost of $9T and $6K must be $168 we can write this as:
$9K + $6T = $168
Answer:
Rate of interest = 10.95%
Step-by-step explanation:
Given:
Amount deposit in bank = 25,000
Number of year = 60 year - 40 year = 20 year
Future value = 200,000
Find:
Rate of interest
Computation:
A = P[1+r]ⁿ
Future value = Amount deposit in bank[1+Rate of interest]ⁿ
200,000 = 25,000[1+r]²⁰
8 = [1+r]²⁰
1.1095 = 1 + Rate of interest
Rate of interest = 0.1095
Rate of interest = 10.95%
