Gliberia 's one time investment =145$
Now she pays 3$cleaning products each time she washes a car.Her profit each time would then be 12$, but she only starts making profit when her cost of advertising is earned /compensated.
Therefore she will not make any profit till the 145/12=12th(approx) time she washes a car.From the 13th time she washes a car ,she stars earning a profit of 12$ each time!
Hope you find it useful :)
Answer:
what is this
Step-by-step explanation:
Answer:
A) $15t - $700 ≥ $1000
B) At least 114 tickets
C) As the attached graph
Step-by-step explanation:
The 7th grade class is putting on a variety show to raise money.
It cost $700 to rent the banquet hall that they are going to use.
If they charge $15 for each ticket,
We are to find how many tickets they need to sell in order to raise at least $1000.
Let the number of tickets they need to sell be t.
The inequality that represents this situation is;
$15t - $700 ≥ $1000
The least number of tickets they can sell is;
$15t ≥ $1000 + $700
$15t ≥ $1700
t ≥ 113.3333 (rounded to four decimal values)
But since we can have 0.3 tickets the class will have to sell at least 114 tickets
The graphed situation is as attached. We need the shaded region.
Answer:
It's B
Step-by-step explanation:
-a +5a-a =3a
+4-6=-2
= 3a-2
Sub all the values in as if input is the x value
A) 1-3 = -2 works
2-3 = -1 doesnt work
B) 2-4 = -2 works
4-4 = 0 doesnt work
C) 3-5 = -2 works
6-5 = 1 works
9-5 = 4 works
12-5 = 7 works
hence C is the answer 3x - 5
