John has a gift card of $100. He spends $5 per day. Write an equation to show the amount left on the card after x days

y = 100 - 5x

Step-by-step explanation:

Total amount of gift card = $100

Amount spent per day = $5

Number of days = x days

Write an equation to show the amount left on the card after x days

y = 100 - 5x

Where,

y = amount left on the gift card

x = number of days

For example,

Assume x = 2 days

Amount left on the gift card, y

y = 100 - 5x

y = 100 - 5(2)

= 100 - 10

= 90

y =$90

he has now walked a total of what?
