Solving Inequalities and Two-Step Equation

Cell plan A is $40 plus $.04 each text
Cell plan B is $30 plus $.09 each text
Write an inequality that shows when plan A is greater that plan B

• 40 + .04x > 30 + .09x

• 40 + .04x < 30 + .09x

• 40 + .04 > 30 + .09

• 40 + .04 < 30 + .09

Sue's lunch account has $25 and she spends $2.50 every day. Troy's lunch account has $50 and she spends $3.25 every day. Write an inequality that shows when Sue's account will be more than Troy's.

• 25 - 2.5d > 50 - 3.25d

• 25 - 2.5d < 50 - 3.25d

• 25 + 2.5d > 50 + 3.25d

• 25 + 2.5d < 50 + 3.25d
