Question

Marco needs $57 to buy new basketball shoes. If Marco earns $3 per day working and already has $12 saved, which equation shows how many days Marco must work before he can afford the shoes?

Answer 1

3x+12=57

x= how many days

Explanation:

Answer 2

`3x+12=57`

Explanation:

Let x represent number of days.

We have been given that Marco earns $3 per day working. So amount earned in x days would be
`3x`.

We are also told that Marco already has $12 saved, so total amount saved by Marco in x days would be
`3x+12`.

Now we will equate total amount saved by Marco in x days with 57 as Marco needs to save $57 to buy new shoes.

`3x+12=57`

Therefore, the equation
`3x+12=57` shows the number of days (x) that Marco must work before he can afford the shoes.
