Answer:

Step-by-step explanation:

It is a bit ambiguous. I'm assuming that what they want you to do is to substitute

y = 140

x = 4  

Into the two equations that went into making the answer of 4 come up

y = 30x + 20

y = 30*4 + 20

y = 120 + 20

y = 140 which is in agreement with your answer

==========

y = 15x + 80

y = 15*4 + 80

y = 60 + 80

y = 140

==============

Conclusion

both equations give the same answer. Both equations are correct.

Answer:

So both equations are true

Step-by-step explanation:

#4 was asking you to substitute x = 4 into both equations to see if it's the solution of the equations.

Substitute x = 4

Ritz equation

y = 30x  + 20

y = 30(4) + 20

y = 120 + 20

y = 140

Smits equation:

y = 15x + 80

y = 15(4) + 80

y = 60 + 80

y = 140

Both companies charged same price  $140 for 4 days

So both equations are true
