1/13 Sandra has a $20 itunes gift card and spends $3 each month. Which equation can be
used to find how much money Sandra has on her giftcard after x months?

The equation that can be used will be y = 20 - 3x

Amount of gift card that Sandra has = $20

Amount spent each month = $3

Let the remaining amount be represented by y

Therefore, the amount that will remain after x months will be deducted from the original amount that she has which will be:

y = 20 - (3 × x)

y = 20 - 3x
