Answer:
40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.
Step-by-step explanation:
Given that:
Hourly rate = d 
Earning to first 40 hours = 40d 
Earning of more than 40 hours = 1.5d 
Amount paid per week = $770 
Hours worked = 50 hours 
first 40 hours + 10 hours = total earned 
40d + 10(1.5d) = 770 
Hence,
40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.
 
        
             
        
        
        
She played 8 games. Since she earned a total of 120 points and 15 points per game you would divide 120/15=8
        
             
        
        
        
Answer:
 3 strain would still alive after 48 hours
Step-by-step explanation:
Initial population of virus = 40000 grams 
A certain virus is dying off at a rate of 18% per hour. 
We are supposed to find  how much of the  strain would still be alive after 48 hours
Formula : 
 =Initial population
=Initial population
N(t)= Population after t hours 
r = rate of decrease = 18% = 0.18
t = time = 48 hours 
So,the  strain would still be alive after 48 hours=
Hence 3 strain would still alive after 48 hours
 
        
             
        
        
        
Hi,
Here is the solution.
3 years = 36 months
Leased amount for 3 years = $3000 + 36*350
= $3000 + $12600
Leased amount for 3 years = $15600
Residual value = $12000
Assume you didn't buy the car, you took it for lease, so your expense = $15600.
Now Assume you bought the car for $21,000.
After using 3 years, you can sell it for $12000.
Your expense = $21,000 - $12,000 = $9000.
Conclusion:
It is less expensive to buy the car.
The cost for buying the car and selling it after 3 years = $9000.
Hope you will understand the steps. Thank you :)
