5x + 300y = 178
4x + 500y = 197

Multiply the first equation by 5 and the second equation by -3.

25x + 1500y = 890
-12x - 1500y = -591 Subtract.
------------------------------
13x = 299 Divide.

x = 23.

Solve for y by plugging in 23 for x.

4(23) + 500y = 197

92 + 500y = 197

500y = 105

y = .21


The Daily Fee is $23 and the Charge Fee per mile is $0.21.

romanna [79]

This problem is about componded interest. The formula for compounded interest is:

\begin{gathered} \text{Amount}=\text{Initial}\cdot(1+r)^t \\ \text{Where,} \\ \text{Amount is the total acumulative at time t.} \\ \text{Initial is the initial amount, at t=0} \\ r\text{ is the interest in decimal number.} \\ t\text{ is the time accordingly the interest, in this case is in years.} \end{gathered}

In this case, Initial = 300, r = 0.06 and t=10 so the total amount in the account after 10 years is:

\begin{gathered} \text{Amount}=300\cdot(1+0.06)^{10} \\ \text{Amount}=300\cdot1.06^{10} \\ \text{Amount}=300\cdot1.79085 \\ \text{Amount}=537.255 \end{gathered}

The amount after 10 years is 573.26.
