A rental car agency A charges $40.00 per day plus $0.15 per mile. Rental car agency B charges $26.00 per day plus $0.10 per mile. Which inequality could be solved to determine when Company B will cost more than Company A?

• 40 + 0.15x < 26 + 0.10x

• 40 + 0.15x > 26 + 0.10x

• 40 + 0.15 < 26 + 0.10x

Mary has been offered two jobs. Job A has a starting salary of $46,000 and a raise of $2000 every year. Job B has a starting salary of $29,000 and a raise of $2500 every year. Write an equation to determine how many years would Mary's salary be the same at both companies.

• 46,000 + 2,500x = 29,000 + 2,000

• 46,000 + 2,500x = 29,000 + 2,000x

• 46,000 + 2,000x = 29,000 + 2,500

• 46,000 + 2,000x = 29,000 + 2,500x

The Rug store installs carpet for $80 plus $11.50 per square yard of carpet. The Magic Carpet charges $100 for installation and $7.50 per square yard of carpet.

• 80+11.50x > 100+7.50x

• 80+11.50x < 100+7.50x

• 80x+7.50x > 100x+11.50x

• 80x+7.50x < 100x+11.50x
