Answer:
x - 31 
69
Tonisha has to make at least $100 in revenue
Step-by-step explanation:
Set up the inequality:
x - 31 represents her profit
Since she wants to make at least $69 a day, use 69
So, the inequality is x - 31 69
Then, solve for x to find how much she has to sell:
x - 31 69
x 100
So, Tonisha has to make at least $100 in revenue
Answer:
$65,000
Step-by-step explanation:
The question asks to calculate the contribution margin for the month of March.
The contribution margin is mathematically calculated as the selling price per unit minus the variable cost per unit
According to the parameters in this particular question, the contribution margin is selling price - total variable cost = 160,000 - 95,000 = $65,000
Answer:
the mean is 8 and the absolute deviation is 1.5
Step-by-step explanation:
to find the mean you add up all the numbers, then you just divide by how many numbers there are. in this case, you would do 64/8 which would then equal 8. then you see how much the numbers differ from the mean. like for your numbers, for 8 it would be 0, for 9 it would be 1, for 7 it would be 1, for 6 it would be 2. you see it? its just how far away it is from the mean. so once you do that, you should have a 6. then you do 6/4 which is 1.5. hope this helps!
4.5w = 5.1w -30
4.5w - 5.1w = 5.1w - 5.1w -30 (subtracted 5.1w on both sides)
4.5w - 5.1w = -30 (next combine like terms)
-0.6w = -30 (next do the inverse operation of w)
w = -30 ÷ -0.6
w = 50 (it became positive cause minus and minus = positive)
so your final answer is: w = 50
Hope that helps:D
