Jan baked 20 trays of cookies for a party. Each tray had 16 cookies on it. She threw away 22 cookies that broke when she took them off the pan.
Which equation shows how many cookies she had left for the party?
Total cookies before throwing away = 20 trays * 16 cookies/tray = 320 cookies
Cookies left after throwing away = 320 cookies - 22 cookies = 298 cookies
Therefore, the equation that shows how many cookies Jan had left for the party is:
320 - 22 = 298
