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
To address this issue, the procedure below should be utilized:
1- The Law of sines can be applied as follows:
The unknown angle can be determined by: 180°-65°-45°=70°
- The <span>distance Jake travels to the store is:
30/Sin(70°)=x/Sin(45°)
x=22.57
- The distance Maddie travels to the store is:
</span>30/Sin(70°)=y/Sin(65°)
<span> y=28.93
- The difference calculated is: 6.36
Thus, the result shows that the difference is 6.36 m.</span>
According to the rule of 72,
72/rate=time
72÷9.6=7.5 years
An alternative method for resolution using the main formula
2300=1150(1+0.096/4)^4t
Isolate t
t=((log(2,300÷1,150)÷log(1+(0.096÷4))÷4))=7.31 years
I hope this is helpful:-)
38 % of the total budget goes to advertising on broadcast TV
Solution:
Based on the details,
Expenditure for broadcast TV advertising = $ 22, 000
Expenditure for cable TV advertising = $ 30, 000
Expenditure for radio advertising = $ 6000
Need to determine: the proportion of broadcast TV advertising
Total expenditure = $ 22, 000 + $ 30, 000 + $ 6000
Total expenditure = $ 58000
proportion of broadcast TV advertising = 

Hence 38 % of the total budget is allocated to broadcast TV advertising
