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

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

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

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

Hence, the price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.
Multiply by 100
0.63×100=63 and then add a percent sign to get 63%
It’s the first one bc if u add -3 to the input it gives the outputs
