Answer:
- The profit can be expressed as 70x + 50
- If 240 phones are sold, the profit amounts to $16,850
Detailed explanation:
The revenue function R(x) is provided as 
The cost function C(x) is given as 
Profit is calculated by subtracting cost from revenue, expressed as Profit = Revenue − Cost
We substitute the given revenue and cost functions into this formula.
Denote the profit function as P(x).
Therefore, the profit function formula simplifies to 70x + 50
Since x denotes the quantity of phones sold, to find the profit when 240 phones are sold, we substitute x = 240 into the profit expression above.
Hence, selling 240 phones yields a profit of $16,850
The final amount Alfredo paid for the fishing pole is $40.4. Step-by-step explanation: The original price of the fishing rod is $97, which has a 60% discount. The discount amount equals 60% of $97, calculated as 0.60 × $97, totalling $58.2. To find the price before tax, subtract the discount from the original price: $97 - $58.2 = $38.8. Now, applying the sales tax of 4%: 4% of $38.8 is calculated as 0.04 × $38.8, equalling $1.552. Adding this tax to the price before tax gives us the total price of $38.8 + $1.552, which rounds up to $40.4.
Each month she puts in 20......therefore annually she deposits (20 * 12) = 240 y = 240x + 200
In a semicircle, there exist pi radians, whereas a full circle consists of 2pi radians. Since 2pi equals approximately 2*3.14, it results in roughly 6.28 radians in half a circle. The total of 2pi radians corresponds to 360 degrees.
