multi-step inequalities

NEXT
3(4x - 5) = -39
Graph with a closed circle.Boundary point included in solution set.
Graph with an open circle.Boundary point is NOT included in solution set.
NEXT
recall
Flip the sign when you divide or multiply across the inequality by a negative!
NEXT
recall
Use the same steps to solveRemember to graph!

real world scenario
Car rental company A charges an initial fee of $200 plus $65 per day to rent a vehicle. Car rental company B charges an initial fee of $250 plus $55 per day to rent a vehicle. For how many days will renting a vehicle from company A cost less than renting from company B?

Which inequality represents the scenario:Carwash A charges $25 for the outside and $3 per inside window. Carwash B charges $30 for the outside and $2.50 per window.When is Carwash A less expensive than Carwash B?A. 25 + 3w > 30 + 2.50wB. 25 + 3w < 30 + 2.50wC. 30 + 2.50w < 25 + 3w
