Isabelle Rangel · Answer 1

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
