The total cost depends on:
1. Software cost
2. each yearbook cost
<u>Variables:</u>
Let the total cost be (y) and the cost of each yearbook be (x).
To print x yearbooks, it's going to cost 15x
Also, there is software (fixed cost) cost of 800
So total cost would be:
y = 800 + 15x
Answer:
<h2>
first piece: 5 in</h2><h2>
second piece: 10 in</h2><h2>
third piece: 32 in </h2>
Step-by-step explanation:
x - the length of the <u>first piec</u>e
2x - twice the length of the first piece (the length of the <u>second piece</u>)
6x - six times the length of the first piece
two inches more:
6x+2 - the length of the <u>third piec</u>e
first + second + third = 47 in {total length of the pieces of steel}
x + 2x + 6x + 2 = 47
9x + 2 = 47
9x = 45
x = 45:9
x = 5 in
first piece: 5 in
second piece: 2×5 = 10 in
third piece: 6×5 + 2 = 30 + 2 = 32 in
