Pick a Solution for Equations and Inequalities

You have $137.26 in a bank account. The bank requires you to have at least $50 in your account or else you are charged a fee. Write and solve an inequality that shows the amount you can write your next check for without being charged.

• x < $87.26

• x ≥ $76.51

• x ≤ $87.26

• x ≤ $187.26

  x+y=33

• x=7y-8
  x+y=33

• 7x+8y=33
  x+y=n

• 2+x=33
  x=8y-7
