To solve this question, we first need to find out the total amount that the 6 friends payed. We can do this by multiplying the amount each one of them payed by the number of friends there are. Since there are 6 friends and they each payed $10, we know that the total payed is $60. 

Now, we need to find the amount that the 6 friends over-payed, which can be derived by subtracting the amount they payed and the amount they were supposed to pay. 

$60 - $41.88 = 
=$18.12

Now that we know how much they over-payed as a group, we need to find out how much each of them over-payed individually, which will be the money they get back. This can be solved by dividing the amount they over-payed as a group by the number of friends.

$18.12 / 6 =
=$3.02, meaning that they each will get back $3.02

Find the solution of the differential equation dy/dt = ky, k a constant, that satisfies the given conditions. y(0) = 50, y(5) =
irga5000 [103]

Answer:  The required solution is y=50e^{0.1386t}.

Step-by-step explanation:

We are given to solve the following differential equation :

\dfrac{dy}{dt}=ky~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

where k is a constant and the equation satisfies the conditions y(0) = 50, y(5) = 100.

From equation (i), we have

\dfrac{dy}{y}=kdt.

Integrating both sides, we get

\int\dfrac{dy}{y}=\int kdt\\\\\Rightarrow \log y=kt+c~~~~~~[\textup{c is a constant of integration}]\\\\\Rightarrow y=e^{kt+c}\\\\\Rightarrow y=ae^{kt}~~~~[\textup{where }a=e^c\textup{ is another constant}]

Also, the conditions are

y(0)=50\\\\\Rightarrow ae^0=50\\\\\Rightarrow a=50

and

y(5)=100\\\\\Rightarrow 50e^{5k}=100\\\\\Rightarrow e^{5k}=2\\\\\Rightarrow 5k=\log_e2\\\\\Rightarrow 5k=0.6931\\\\\Rightarrow k=0.1386.

Thus, the required solution is y=50e^{0.1386t}.
