Question

Choose a relationship model that will reach $0 in the same number of days as this scenario: Mika has $12 and spends $2 each day.

y = –2x – 12
y = –3x + 18
y = –4x + 12
y = –12x + 2

Answer 1

y= -3x + 18

just took the test lol

Answer 2

Answer: Hence, our required expression would be
`y=12-2x`

Explanation:

Since we have given that

Amount that Mike has = $12

Amount he spends each day = $2

Let the number of days be 'x'.

Let the amount remaining at the end be 'y'.

So, According to question, it becomes,

`y=12-2x`

Hence, our required expression would be
`y=12-2x`
