Hayla had $22.45. She bought a notebook for $2.20 and a pack of pens for $4.35. Write an expression to match the words above.

Answer 1

The beginning of the question says that Hayla HAD $22.45. This means that this was the amount of money before buying anything. Then, she brought a notebook that was $2.20 and a pack of pens that were $4.35. Because she brought these things, she has to pay money which means you must subtract these two numbers from the money she already had. This means your expression will be:

$22.45 - $2.20 -$4.35 = $15.90
