Question

Anne had 65 cents. She found 25 cents on the sidewalk. She bought a bag of chips for 55 cents How much money did Anne have then?

Answer 1

She ends up with 35 cents.

Explanation:

Anne starts with 65 cents.

She finds 25 cents on the sidewalk, so after that she has:

`65+25=90`

And then she buys a bag of chips for 55 cents:

`90-55=35`

She ends up with 35 cents.

Answer 2

35 cents

Explanation:

Breaking the question down into its component parts.

Ann had 65 cents:`" ....................... "->65`
She found 25 cents:`" .................... "->65+25`
bought a bag of chips for 55 cents:`" "->65+25-55`
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`color(blue)("This is one of several methods")`

Regroup the numbers: `" "color(green)(25+color(red)(65)-55)`

Split (partition) the `color(red)(65)" into "color(red)(10+55)" "` giving:
`color(white)(.)`

`color(green)(25+color(red)(65)-55)" becomes "color(green)(25+color(red)(10+55)-55)`

But 55 - 55 =0 giving:

`25+10+0" "=" "35`
