leonid [27]

hello

from the question given, the dog walker charges a flat rate of $6 and an extra $30 per hour.

we can write out an equation in function notation

let the number of hours be represented by x

$f(x)=6+30x$

now we can proceed to solve the cost of the walk for 45 minutes

$\begin{gathered} 1hr=60\min s \\ \text{xhr}=45\min s \\ x=\frac{45}{60} \\ x=\frac{3}{4} \\ \text{therefore 45mins = 3/4 hours} \end{gathered}$

now we can input the value into the equation and know the cost for 45 minutes walk

$\begin{gathered} f(x)=6+30x \\ x=\frac{3}{4} \\ f(x)=6+30(\frac{3}{4}) \\ f(x)=6+22.5 \\ f(x)=28.5 \end{gathered}$

from the calculation above, the cost of 45 minutes walk will cost $28.5

The price, e, of an entertainment system at extreme electronics is $220 less than twice the price, u, of the same system at ultr

MrMuchimi

Answer: The price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.

Step-by-step explanation:

Let the price of the system at the ultra electronics be u

Let the price of the system at extreme electronics be e

According to question, we have

$2u-e=220\\\\and\\\\e-u=175$

Now, using the substitution method, we will solve the above system of equations.

$e-u=175\\\\e=175+u$

Now, put the value of u in the first equation :

$2u-e=220\\\\2u-(175+u)=220\\\\2u-175-u=220\\\\u-175=220\\\\u=220+175\\\\u=\$395$

Now, we put the value of u in the equation which is given by:

$e=175+u\\\\e=175+395\\\\e=\$570$

Hence, the price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.
