Answer:
30 and 20 respectively
Step-by-step explanation:
Let the number of sofas to be built be s and the number of recliners be r.
For the time part, we have the following equation:
8s + 6r = 340
For the money part:
180s + 105r = 6750
Now let’s solve these equations simultaneously.
Let’s change the form of the second equation:
180s + 17.5(6r) = 6750
From the first equation, 6r = 340 - 8s
Insert this into the third equation
180s + 17.5(340-8s) = 6750
180s + 5950 - 140s = 6750
40s = 6750 - 5950
40s = 800
s = 20
Substitute the value into the first equation
8(20) + 6r = 340
6r + 160 = 340
6r = 180
r = 30

Answer:
54 degrees
Step-by-step explanation:
If these two lines are parallel, than angles 1 and 7 are supplementary.
13x+9+5x+9=180
18x+18=180
x+1=10
x=9
Angle 6 and 7 are vertical angles, so they are equal. Therefore, angle 6 is:
5x+9=5(9)+9=54

i = interest 3% for 30 years
This is a simple dynamical system for whom the the solutions are given as

putting values we get
S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)
= $98005.35
withdrawal of money takes place from one year after last payment
To determine the result we use the present value formula of an annuity date

we need to calculate R so putting the values and solving for R we get
R= $6542.2356
