Answer:
$54
Step-by-step explanation:
First
45 times .05= 2.25
Second
45 plus 2.25
Third
45 times .15= 6.75
Fourth
45+2.25+6.75
$4.15n - ($250 + $2.45n)
Now that we have our expression, let's set it greater than or equal to 0
$4.15n - ($250 + $2.45n) >= 0
Let's simplify the left side.
$4.15n - $250 - $2.45n >= 0.
Combine like terms.
$1.7n - $250 >= 0
Add $250 to both sides.
$1.7n >= $250
Divide both sides by $1.7
n >= 148
You would need to make 148 light sabers to make a positive profit.
30+4+.1+.02-.007 is the answer.
