Question #0c319

Answer 1

See the entire solution process below:

Explanation:

We can rewrite this problem as: 15% or what is $2.55?

"Percent" or "%" means "out of 100" or "per 100", Therefore 15% can be written as `15/100`.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the amount we are looking for "a".

Putting this altogether we can write this equation and solve for `n` while keeping the equation balanced:

`15/100 xx a = $2.55`

`color(red)(100)/color(blue)(15) xx 15/100 xx a = color(red)(100)/color(blue)(15) xx $2.55`

`cancel(color(red)(100))/cancel(color(blue)(15)) xx color(blue)(cancel(color(black)(15)))/color(red)(cancel(color(black)(100))) xx a = ($255.00)/color(blue)(15)`

`a = $17.00`

The bill was `$17.00`
