To earn a profit, the revenue must be greater than the cost. The revenue for selling x units of an item is R = 26.05x. The cost
zheka24 [161]

Answer:

a. Yes. The owner made a profit, because R > C when x = 183.

Step-by-step explanation:

(1) Calculate the revenue

R = 26.05x = 26.05 × 183 = 4767.15

(2) Calculate the cost

C = 1500 + 16.75x = 1500 + 16.75 ×183 = 1500 + 3065.25 = 4565.25

(3) Calculate the profit

P = R – C = 4767.1 – 4565.25 = 201.90

P > 0. The owner made a profit, because R > C when x = 183.

In the graphs below, the red line represents costs and the blue line represents revenues.

We see that C > R until we reach the break-even point at 162 units. After 162 units, R > C, and the business makes a profit. This, making 183 units is profitable for the company.

fgiga [73]

Answer:

0.3125

Step-by-step explanation:

If it decreases by 50% each time it hits the ground then all you have to do is divide 10 by 2 (50%) each time it bounces.

10 / 2 = 5 (first bounce)

5 / 2 = 2.5 (second bounce)

2.5 / 2 = 1.25 (third bounce)

Ect. . .

Until on the fifth bounce it is 0.3125m high.

Unity makes $56 a week, plus 15 percent of the cost of meals that she serves. Use the equation, y = 0.15x + 56, to predict what
seropon [69]
X represents the cost of meals served in a week. The cost of meals or worth was $435, therefore, x = 435. 0.15 x 435= 65.25
Since she makes $56 along with 15% of meals served (which is $65.25), you add those together to get her final income the week she serves $435 worth of meals, so...
66.25+56=121.25
Unity makes $121.25 in a week that she serves $435 worth of meals.
