Answer: the bill for a glass of apple juice is $0.7 and the bill for a salad is $1.5
Step-by-step explanation:
Let x represent the bill for a glass of apple juice.
Let y represent the bill for a salad.
The bill for five glasses of apple juice and four salads is $9.50. It means that
5x + 4y = 9.5 - - - - - - - - - - - 1
The bill for four glasses of apple juice and five salads is $10.30. This means that
4x + 5y = 10.30- - - - - - - - - - - -2
Multiplying equation 1 by 4 and equation 2 by 5, it becomes
20x + 16y = 38
20x + 25y = 51.5
Subtracting, it becomes
- 9y = - 13.5
y = - 13.5/-9
y = 1.5
Substituting y = 1.5 into equation 1, it becomes
5x + 4 × 1.5 = 9.5
5x + 6 = 9.5
5x = 9.5 - 6 = 3.5
x = 3.5/5 = 0.7
Answer:
c
Step-by-step explanation:
C.) I believe is the correct answer
Answer:
Markup = [(Revenue – COGS) / COGS] X 100.
Markup = (Gross Profit / COGS) X 100.
Markup = [(Revenue – COGS) / COGS] X 100.
Markup = [($400 – $250) / $250] X 100.
Selling Price = [(Markup X COGS) + COGS] X 100.
Selling Price = (Markup X COGS) + COGS.
Selling Price = (0.50 X $100) + $100.
Step-by-step explanation:
um i think this is the answer
Median = 75 because that is where the middle line of the box is.
First quartile = 70 because that is what the left edge of the box represents.
Third quartile = 85 because the right edge of the box indicates that.
Maximum = 100 because at the far right is the maximum data point of your data set.
The middle 50% of that data is between 70 and 85 because those are the values the box covers. It goes from the first quartile, 70, and stretches all the way to the third quartile 85.
