$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.
Any whole number is an integer but here are some examples: 1,5, 8, 97.
Answer:
9
Step-by-step explanation:
The equation is
9x + 1.50 = 82.50
You must isolate the 9x , to do so you have to subtract 1.50 from both sides.
9x + 1.50 = 82.50
-1.50 -1.50
9x = 81
isolate the variable (x), to do so you have to divide both sides by 9
9x = 81
/9 /9
=
x = 9
You use the FOIL method for this problem. you should get X^2-25
