Question

Your friend offers to pay you $10 plus $2 per day if you will watch his dog while he's on vacation. Ant hot her friend offers you $15 plus $1 per day to watch her dog during the same time. You cannot do both jobs. Tell which job you would choose and explain why.

Answer 1

Well it depends on how long the vacation, but let’s say it was a week long trip then the first option would pay more with 24$ instead of 22$. But if it’s a short vacation definitely the first one

Answer 2

Explanation:

Let x represent the number of days for which you will watch the dog. Assuming x is the same for both offers.

Your friend offers to pay you $10 plus $2 per day. Considering the offer of your friend, the total amount that you will receive for this offer will be

10 + 2x

Her friend offers you $15 plus $1 per day. Considering the offer of her friend, the total amount that you will receive for this offer will be

15 + x

Looking at both offers, the offer of your friend would yield more income as the number of days increases. This means that as x increases, the income will from your friend's offer will increase
