Respuesta :
The designers will Charge the same amount at $700. 500+100*2=700 and 600+50*2=700
Answer:
They will charge the same cost after 2 hours.
Step-by-step explanation:
Using the problem values, we can find an expression to each designer cost, and then solve the system.
Designer A: [tex]y=500+100x[/tex]
Designer B: [tex]y=600+50x[/tex]
The amount that has to be with the variable is the fee per hour, because we don't know the number of hours. Now, we solve this system to find the common point, we equalize both equations, because the problem is asking for the moment when the charge the same price [tex]y[/tex]:
[tex]y=y\\500+100x=600+50x\\100x-50x=600-500\\50x=100\\x=\frac{100}{50}=2[/tex]
This means that they will charge the same cost after 2 hours.
