Question

An insurance company paid $320 to Heather in compensation for her stolen camera. If this was 80% of its value, what was Heather's camera worth?

Answer 1

camera was worth: `$400`

Explanation:

Given: `80%` of a camera's value is `$320`. Find value

`%` equation: `%/100 xx "of" = "is"`

Use the variable `V` for `color(red)("of")`, the total value.

`80/100 xx V = 320`

`V = 320/1 * 100/80 = $400`

Answer 2

`$400`

Explanation:

Notice that `$320` is `80%` of the camera's value. Let the camera cost `$a`.

So, we get:

`80%*$a=$320`

`0.8a=320`

`a=320/0.8`

`=400`

Therefore, the camera was originally worth `$400`.
