A rental car agency charges $30.00 per day plus per mile $0.15. Another rental car agency charges $36.00 per day plus $0.10 per mile. How many miles would have to be driven in one day for both rental agencies to cost the same amount to rent? 

• 120 miles

• 100 miles

• 110 miles

• 150 miles 

What equation is modeled?  Solve the equation.

• x -6 = 13     x = 19

• x + 6 = 13    x = 7

• x + 6 = 13    x = 8

• x - 6 = 13   x = 7

Blind company A charges $25.00 to install blinds for one room and $5.00 for each additional window. Blind company B charges $30.00 to install blinds in one room and $4.00 for each additional window. Write an inequality that can be used to determine When Company B will cost more than Company A.

• 25 + 5x < 30 + 4x

• 25 + 5x > 30+ 4x

• 30 - 25 = 4x + 5x

• 25x + 5 > 30x + 4
