Question

There are 480 soccer balls on a field. Every hour, half of the balls are put back into the locker room. Write an equation that can be used to find the number of soccer balls remaining on the field at the end of x hours.

Answer 1

`y= 480-0.5x`

Explanation:

Given data

Number of balls= 480

we are told that 50%(half) of the balls are put back every 1

let the number of hours be x

and let the remaining ball be y after x hours

Hence the expression is given as

`y= 480-0.5x`
