Ms. Jaber goes shopping and spends a total of $45.32.  She now has $32.25 left on her gift-card. Which equations can be used to determine how much money Ms. Jaber had on the gift-card before she went shopping? Select each correct answer.

• x = 45.32 - 32.25

• x + 32.25 = 45.32

• x - 45.32 = 32.25

• x = 32.25 + 45.32

• x = 32.25 ÷ 45.32
